Why so much hate about the first two sequels?

Most of us on these forums like TLW, so I can't rearly answer that one. The San Diego scene, perhaps the darker tone, I really don't know why people hated it.

JP3 however, is a different story. They killed Rex in under a minute of total BS, they gave no information on the Spinosaurus other than it's a big mother f*cker that can't do anything against wood, there was little character development, the characters weren't very likeable, there wasn't much of a plot, it was inconsistent, and there was no logic in parts (that phone surviving perfectly in tact after getting eaten).

Well, I never see much hate on TLW (it's my favorite JP film), but JP3 wasn’t a great movie. It was okay at best. 

Personally, I give the first movie a 10/10. TLW gets a 7/10 and JP 3 gets 5/10. I liked TLW just fine and JP 3 was an OK movie, I just don't think it was a great Jurassic Park(if that makes sense).

Like Mr.Happy said theres no mush hate to TLWJP, but the 3d movie is hated for inconcistencies, an unrealistic spino, Unlikable characters and so on

I actually like TLW very much, but the scene where the ship crew are dead is just too confusing for me

and about JP3, I don't hate it either, I just dislike it because the plot is too shallow, and amanda kirby didn't die
the dinos are awesome though

the lost world is actually my favorite of the movies. the third was just dissapointing. it had its moments but i just didnt like it as much

For me  TLW really started to suck during the raptor attack in the tool shed when Ian' Malcolm's daughter's gymnastic routine kills the raptor. I dont know what happened in the book but I wasnt too crazy about dinosaurs leaving the island either. 

The animatronics for the Spinosaurus looked horrible compared to Trex in JP n TLW 

I think people's expectations were so high for the sequals becuase Jurassic Park was and still is the grestest movie ever created !!!!

I can agree with what jpjoe84 said as well.

I actually like the first two sequels, Lost World is great! But JP3 has its downfalls, many in fact, but I'm pretty sure they already told you. Now, I don't hate these movies, they are by far, better than a lot of movies I've seen, they're just not as good as JP1.

I thought that The Lost World was just as good as the first one! The third was just simply okay.

Well i believe the dinosaurs on JP3 got improved a lot. the T-rex looked more realistic than the 1st movie and for me the battle scene (and for maanyyy others) is one of the greatest scenes not only from the franchise but from every movie out there! Let us not forget that it isn't that easy to make up a story that would bring the characters for the 3rd time to the park and steven was not even directing. now about the cast, i think the fact that Sam Neill is staring its just dope :D (ma opinion)... and of course every movie has its ups and downs!

p.s. the spino rules even though i am team rex ;p

I myself hate the fight scene with a passion. It was a thirty second BS fest. The result itself wasn't what pissed me off, but how it happened. 

IN agree with Mr.H, Spinos don't have great bite force, and the bite on the neck that the rex gave him would of killed it

well Jurassic Park itself can't be realistic. Don't look deeper into details. At least they added "feathers" to the Velociraptors... They were as realistic as the could.

I personal love the trilogy and it's my favorite movie franchise next to The Dark Knight trilogy.

Jurassic Park is just magical. The dreams of seeing a dinosaur in front of your eyes. It had some flaws (like how Rex pushed the car into a cliff?) but it was still awesome.

NOW The Lost World was, in my opinion, a bit of a let down. Choosing Malcom over Grant was a big mistake IMO. Still love it but a lot of the stuff made no sense. It was still a enjoyable movie nethertheless.

Jurassic Park 3 was a bit of a let down as well. For starters, it was shorter than the first two! Haha but the action scenes were way better like the Bird cage part, plane crash etc. Plus it introduced a awesome new needed villain: Spinosaurus. Rex fanboys were honestly just hating on that movie because of that fight scene 80% of the time.

I'll have you know, JP 3 is 1.5 hour BS fest. Sure, it had some interesting scenes, but for the most part, it is total BS. They killed the character of Alan Grant, they had very little plot, and they had random, pointless CGI shots. On top of that, the whole replacing Rex deal was total BS in the way they did it. 

Honestly, I'm fine with TLW, it's JP3 that Bugs me, for so many reasons. First of all, IMO spino was a terrible choice for a villian, for many reasons (fish eater, almost useless teeth) I myself would have preferd a Giganotosaurus, Carcharadontosaurus or even a Allosaurid of some kind for multiple reasons. 

There pack hunters, instead of a one on one battle it could have been a 3 vs 1. Making the rex fans less disappointed and it would avoid controversy. And there similar to rex, but, not the same. They have a different bulid, different looking skull, faster. 

And don't get me started on the plot.. It was terrible to say the least, almost no character devlopment.

There so many inconsistencies, spino can destroy a plane, a massive stell fence but, his weakness is WOOD! Trees and wooden doors are immune to the spinosaurus, if they ever recreate a Spinosaurus, and if I get to see it I'm bringing a stick for protection.

Honestly the biggest problem for ME with the movie is that pretty much evreything in that movie, Jack Horner decided. IMO, the only reason he's so famous is that he discovred sevral rex skeltons, a dinosaur he hates, for some unknown reason.

 Rex fanboys were honestly just hating on that movie because of that fight scene 80% of the time.

All i can do is roll my eyes at this.

 Plus it introduced a awesome new needed villain: Spinosaurus

And you tell me you aren't a spinosaurus fanboy? based on this, and your other posts... that is quite the contrary,

  That movie was a poor cinematic representation of what a jurassic park film should be, end of story.

About the whole 80% remark; by saying that, you are implying that at the same time, 80% of Spino fanboys loved the movie because of that fight.
