Seeing it a second time, I really did envision the perfect fan-edit in my head (which I'll do as soon as the 3D Blu comes out - kind of like my 60 minute Catwoman version of Dark Knight Rises that I love). I wish they had just not bothered at all with the "character moments" - they are forced, and the film doesn't need them. I would have felt just as scared for the kids just because they were kids, I didn't need to know about their crappy home life.
That won't fix some of the directing issues - watching it a second time, making sure I hadn't missed anything the first time, there were a good 3 times during the film where I wanted to just smack the director upside the head and say "WTH??": the opening monorail sequence, inside the T-Rex attraction, and the "behind the amber" portion of the finale. I got what he was trying to do - subvert audience expectations - but what he was trying to do just sucked, LOL - you can't do that in a picture like this and not payoff. It just came across as "I want to be an arty director and not make a cookie cutter film" when if any film needs that cookie cutter precision, it's one like this.
Overall, still rather satisfied - heck, already ordered the Blu-ray - it definitely had a lot of good (and some great) to it. I think there is a good 85-minute film there, and hopefully there will be some deleted scenes on the home release of some more attractions - that was the other big thing, it felt like they spent way more time in lines than in attractions.
