He asked that question for very important point.
@Post Ironic I get why some would take it as you did With this being only exposure to Deadpool THE character. But however small or big, for those who know the cartoon, videos or more importantly the comic, this IS Deadpool (read comics due to my brother, hence was looking forward to the zany mofo). Movie is 95 procent adaption of the crazy balls out wtf clown that is Deadpool regardless of format he is depicted in (the 5 procent remaining is for toning him down a bit from super r rated at times dark comic, it's not all humor). It's not many comic adoptions can say that.
So it's the least thing one should have with the movie itself (tho it's disjointed and mediocre at times, didn't like how director did the time jumps). Then it basically becomes wether you like the character itself to find him ridiculously funny or obnoxious.
And yeah Reynolds was amazingly well fit for the role. He was born for the role. Basically his career at his best has been this type of funny since Van Wilder. Waste of witty type of actor to do top serious roles or bland rom coms for career reasons.
