Not every movie needs to have a deep message or be made for everyone.

Sometimes, all you need is to see the good guys win, and the bad guys suffer.... a lot.

That is this movie in a nutshell. Well, not the first part, since there are no good guys in such a situation, but the perfect combination of gore and humor is the ultimate pill for your worst "fuck the world" attitute.

Recomendation:
Ignore the movie. Ignore it, until you get that one bad day, and want to see the california burn.

Then, you will see this movie for the 10/10 it really is.
Ignore the bad reviews. This movie will be remembered in decades to come.
