Well here is the thing, the originalwasmagic. But expecting this, or any other movie to ever match that again is absurd. The movie isn't being directed by Spielberg and Michael Crichton is dead, those two put on a magic combination with the first movie. The first movie was so good it resurrected interest in dinosaurs around the world; that is a pretty high bar to set. Were most of the characters in this lackluster? Yup, but to ever expect something to rival the first movie is just setting yourself up for disappointment. The premise for this movie was, in my opinion, the best possible one they could have come up with.
"What would Jurassic Park look like if shit didn't go wrong?", and on that front it delivered. The corporatising of the dinosaurs, and the sterilization of the park to be super family friendly versus the original is actually really compelling if you think about it. Chances are that is exactly what would happen if we had arealdinosaur theme park. So yeah, while they weren't able to recapture the magic of the original, they did pretty damn good with what they got. They realized they couldn't nail down the fantastic characterization/drama of the first, and simply went with action movie instead; which with dinosaurs is a pretty good option.
That said, the series should have ended here. This was the best sequel they could possibly serve up, and the plotline they left open for the sequel that seems to strongly indicate genetic hybrid military dinosaurs is hilariously farcical and will fall on its face. They finally told the story of a working Jurassic Park and outside of sending people to die on Isla Sorna for bullshit reasons like the third movie, that is really all that you can possibly hope to milk out of the original premise without jumping the shark.
