I finally saw this today, and it was an incredibly enjoyable film. I was almost laughing during that final battle between Indominus, the T-Rex, and Blue (was that blue? They all look the same), out of sheer joy. I think Trevorrow managed to almost perfectly emulate the balance that made the original so damn great. The thrills and excitement, the terror, at times, and the sheer wonder of it all.
It wasn't perfect, but it was probably one of the most entertaining films I've seen this summer, and it was damn good. It's kind of amazing how, one second, those raptors were ****ing eating everyone, and the next, you're like "awwwww, he got blown up, damn, Indominus ate him, and so on and so forth." It seems like Trevorrow took J.J.'s concept with the Super 8 Monster and actually managed to make it work.
