Is San Andreas worth going to? I love Dwayne, especially in Fast and Furios - he just rocks (see what I did there? xD)! I went to see the last movie. Nobody stops a drone with an ambulance quite like he did 
I also wanna go to Jurassic World, but I haven't seen the previous, as it turns out, three movies. But I'm not sure it's gonna be relevant to this one, except for the idea - Let's clone dinasour DNA and make amusement park, but also let's alter that DNA so the dinasours are smarter, WHAT COULD GO WRONG?
Did I get it right? 
Cannot judge San Andreas yet, but I have doubts. While I like disaster flics, The Rock, and lovely leading ladies, when CGI becomes so utilized that highly improbable stunts are commonplace, the FX become the focus; not the story. For me, this is the difference between the first trio of Star Wars films and the later ones, and is something that more films seem to do recently.
The original Jurassic park films are wondermous; highly recommended before seeing this next one. Also, check out the dino impersonations of Tom Hiddleston; hilarious!
