The special effects of the original Jurassic Park don't hold up too well now, but the filmaking and tension Speilberg used off-camera (like the iconic water in cup vibration scene) do.

I will definitely see it but I think sequels all fail because instead of telling an expanded story with care, they pack the effort into the spectacle alone...that was why I go a kick out of the quote "why do they always have to be bigger?" from that trailer!
