I hate people who say "oh well this is a good popcorn movie where you don't have to think and there are explosions and boobs and shit" because that excuses goddamn boring action scenes. I can forgive a boring plot. I can forgive boring acting and boring scripts. But if your whole reason for existence is to wow us with your CGI enhanced multi-million dollar action scenes, THEN IT BETTER BE WORTH IT
If you make a 200 million dollar summer action movie, the action scenes better be fucking amazing. I don't want a by the numbers scene that I've seen 50 times before.
I want martial arts fights like the Matrix
I want sword fights like Gladiator or Kill Bill
I want gun fights like the Matrix, Terminator 1 and 2, Hardboiled, Hot Fuzz or Heat.
I want superheroics like the Dark Knight or at least Iron Man
I want giant ass battles like LOTR or Braveheart
If you can't make a movie in that league then fuck you and go home. Your shit is weak and isn't worth the price of a ticket.
