I don't get the hype either. First one was inpressive at its time, and has aged with dignity too. But it was a film focused on an idea (dinosauruses everywhere) and the very well done visualization of it. The script and story itself were pretty silly. I mean, for most of the movie t-rex walking made Trees wave and ground shake and water move in that damn glass and it was depicted massive. And then somehow it just goes ninja and during the finale somehow managed to get totally unnoticed in to the building, from a human size door.
Trailer for the new one just seems bad. Cgi doesn't look anything special, rather bad actually. Man created mutant dinosaurus that "was a big mistake"? That's like any scifi horror action flick starting from the 50s. That basicly also changes the franchise a lot, from now on there can be pretty any kind of monsters, who vaguely resemble dinos. This just seems like any other generic summer blockbuster.
