I guess that's fine for you, but we both differ in that I totally understand why people like your former deadpool. It's because it's the deadpool we've been getting cross-overs of in damn near every fighting game or superhero mash-up game for the last few years. I didn't even learn about a deadpool comic until I heard about this particular game being in development. It's not particularly bad, it's just not the Deadpool you know.
I haven't played Wolverine Origins and I'm assuming that it feels great to play with but, having never played it and basing my experience of beat 'em ups on games like God of War or Hulk, I say that the mechanics are ok. Not great, sure, but I think you'd be more nit-picking at that little detail than anything. Of course it's gonna be considered less than, say, Arkham city when it comes to mechanics. That's the pinnacle of the genre. and has story.
And, sorry, found the ***** slapping Wolverine scene to be funny as hell.
