So I saw it yesterday. Loved it. I'm not a dinosaur buff so all this palaeontologist stuff isn't a bother to me. Even then, the film waves it off with Wu saying that they wouldn't look the same as they do if they didn't have to fill in the gaps in the DNA. It's not Jurassic Park, that's a really important thing to understand. It's not really a remake of the first film. It's a Jurassic Park film (lots of elements from the series) but it's not the first one.
Characters, as stated, were pretty bleh. I loved Pratt and Johnson (but I feel that was probably more because I love them anyway). I did enjoy the way the Raptors and Owen's relationship was handled. It worked really well for me and the whole weaponized story aspect was handled with a very soft touch, I thought. Nothing over the top.
I thought the monster on monster stuff was very fan wanky but again, it worked for me. The I-Rex was believable as genetic crossover has been a thing since the first film. It didn't feel at all out of place.
I really enjoyed it. Plus, no re-used dialogue.
