I got it and sunk in two hours, I'm honestly happy with it...trust me when I say I was pretty worried, this is a game I've been waiting to see made since I was 13 and Deadpool was still one of the most obscure comic book characters out there. I can remember a time where friends that were non comic readers called him "Spider Man with guns" and my friends who were also into comics called him "Dime store Deathstroke" and the issues were damn near impossible to find after issue #17.
The gameplay is nothing special, but even HMS said they weren't looking to reinvent the wheel on several different occasions. Rather they were just aiming to crank out a game about being Deadpool. And that's worked in the past for Marvel, I mean Spider Man 2 was about the Spider Man experience and the Punisher was about being the Punisher. Neither were mind-blowing, but they really put you in the character's shoes. So for that, HMS did great. The story works for a stand alone DP game and it seems like everyone involved was a fan of the character.
If anything, the entire thing reminds me of a Suda 51 game. A game that's highly batshit, stylish, self aware and bare bones when it comes to gameplay. And I love Suda's stuff, so I you'll hear no harsh remarks from my end.
Joe Kelly had a good run, but there was only so long that you could drag out the whole thing with Deadpool going from being a walking South Park episode one second to being The Phantom of the Opera the next. It was something you could only drag out for so long, especially when it came to later issues where he would get some form of closure and have to move on. But to hold Joe Kelly on a pedestal? Sorry, not after T-Ray. I hated T-Ray as an arch nemesis and that convoluted mess that Kelly tried to work into Wade's backstory. The thing that I like about Way's take on the character that started back in Secret Invasion was 1) He gave us the gimmick with Deadpool talking to his narration boxes. 2) The fact that he's pretty much given up on giving a damn about his past. The beauty of Deadpool is for all of his tragedy and skills, he's the comic relief of the Marvel universe. A serious Deadpool is not a good one, I've seen it done more than once. Look at the new Thunderbolts run, that writer sucks at writing Deadpool with sad attempts to create a love triangle with him and Elektra and a seemingly out of place lack of jokes from the Wade Side of the briefing room.
Bottom Line:
If you liked No More Heroes, Mad World or are a fan of (Daniel Way's) Deadpool, give it a whirl.
If you're the type of person that was rolling your eyes at the corny jokes throughout Boarderlands, didn't like DMCs' gameplay mechanics or have a tendency to nitpick, don't waste the money.
