Now, this had all the elements of your typical big budget disaster movie. And since I'm a sucker for such films (Loved them since childhood), I had a really good time with it.
The disaster/destruction scenes were great. Loved them. There were a couple really WOW moments like the Tsunami. And the accompanying soundtrack was good enough to enhance the scenes with feeling of awe and wonder at nature's power at display it. And I'm glad that atleast during disaster scenes, the movie didn't add jokes to ruin the moment (I'm looking at you 2012). The Golden Bridge gets destroyed in a grand fashion yet again, probably the most destroyed landmark in film history. The CGI was mostly top notch. The part where it was the weakest was surprisingly the first scene with the car crash, it looked really fake there.
As far as characters and drama goes, there is always the cheesy/lame family drama and the scientists/government trying to figure it out/makes sense of it part out in these movies. The family drama is almost never good and it was the same here. It was often cheesy/corny and lame and was filled with impossible escape sequences, which is the norm in disaster films. I did like The Rock in his role and as a bonus, we got Alexandra Daddario as his daughter (DEM EYES!!). Also, I liked that the person(s) to be rescued, in this case the daughter, wasn't your typical useless damsel in distress situation. It was refreshing to see her taking the charge in survival and stuff.
The scientists/Government (No government stuff this time) part in these movies is something I always enjoy. Even if the science is wrong, and it is wrong most of the times, I don't care for that. I just like seeing people trying to figure it out or trying to do something about it and also seeing the fear in them when something big is coming. Plus, here, we got Paul Giamatti as the lead scientist and he was pretty good.
All in all, I enjoyed San Andreas. Disaster movies are VERY rare and I love them. Wish there were more of them. Watch it if you wanna see some cool destruction and know what you're getting into.
