I haven't seen Sucker Punch yet, but I really want to. It's supposed to be awful, but I'm contesting that based soley on the fact that I DON'T CARE.
Let's just have a quick overview of things I saw in the trailer that have brought me to this scientific reasoning:

1) Burlesque performers.
2) Guns.
3) Clockwork and steam powered zombie Nazis storming British trenches in the Somme (henceforth to be known as "the Zomme") with WW1 guns.
4) More guns
5) Dirigible assault airships (blimps/Zepplins with guns).
6) Even more guns (including a Lewis gun!)
7) Giant robot ninjas/samurai with GE M134a Vulcan cannon (aka "miniguns").
8) Yet more guns.
9) A mechanised exoskeletal bi-pedal weapons and combat platform (aka a "war walker" or "dreadnought") with a pink anime bunny on the front armour and two self loading autocannon (looked like the 20mm/25mm ones used in old MiG fighters) fighting a squadron of tri-planes. Yeah. TRI-planes.
10) You guessed it. Just when you thought you'd see them all, they bring out further more guns.


So yeah. I don't care about a plot line. Just make sure the explosions are loud and nobody gets annoyed when I say "Holy shit! The Lewis Gun!".
