I am not a comic book fan, yet I like these super hero movies.
I knew nothing about Deadpool but with all the hype around on the Internet I was looking forward to see it.
Deadpool has high ratings everywhere (8.7/10 on imdb, 91/100 on CZ/SK movie server).
Its fun and action (+ hot Morena Baccarin - if you know StarGate Atlantis you know her) and overall, I liked it. Go see it.
Spoiler for possible spoilers:
Is it just me or there's big difference between Deadpool and Wade Wilson?
I mean while he is wearing the mask he's all fun and mocking others, while in plainclothes he is just a common movie guy who got somehow hurt by someone and wants revenge.
Also the movie is making fun of other super hero movies while still being a common super hero movie (with "Deadpool" stuff and behaviour).
