So, we decided to go visit relatives in Alberta and decided to go see this. Loved it, laughed so hard in some spots I had tears and cheered when he did stuff that most movies have the main character hold off on. I'll go again when it hits my home town.
Curious to see that the theatre we went to had it rated 14A, I thought it was rated R. Anyhoo, I don't see a problem with 16 and up going to this, 14-15 year olds, I think it depends on their maturity level so parental discretion should be advised there. Personally, I was reading novels, graphic novels/comics and watching movies at 14 that were just as violent, if not more, and as sexually suggestive, if not more. So if you're a parent and you're wondering if your kid should or shouldn't see it, then go see it, think about what you saw or did when you were your kids age and make your judgement from that.
If you liked this then go play the DeadPool game. Or go play the DeadPool game and then see this movie. Oh, and make sure to stay and watch the little blurp after the credits.
