I just got back from seeing the movie in theaters and I must say, it was pretty good! I wasn't a big fan of the original for some reason, but I decided to give it a shot. I will note that there is a lot of flashing lights in some of the scenes, so if you're sensitive to that kind of stuff, keep an eye out for a scene with Elastic Girl doing a TV interview (this is not a spoiler) where it's really heavy on that.
The Jack Jack scenes were by far my favorite of the whole movie as well.
Otherwise, make sure you get there at the start, PIXAR included a short film before hand which I thought was really great as well. If you saw it or are going to see it, let me know what you thought!
