Outside of Pratt the rest of the cast was pretty terrible imho. Opie's Daughter was brutal in every scene she was in and had zero chemistry with Pratt when they were together. The two brothers were annoying as hell...like when the one who was autistic half the time talked about their parents maybe getting divorced (which was a plot point that had no value and never came up again) and the older brother basically douching him out over it. Everyone else was either completely stupid, evil or both. The movie should have been called "Chris Pratt and the Island of Bad Ideas".
The last half hour was a lot of fun and made up for most of the other 2 hours at least. Personally though I wish the dinosaurs had killed all the people and then fought. Whoever wrote the script must have been drunk or never met a person in real life because not one of the characters was likable or believable. It was an island of Nedrys

I put this a half step above Jurassic Park 3 but leagues behind the original.
