@Risebell Ok, I do kind of get that, though I would like to add something.
Deadpool, while he has been in a lot recently (fighting Carnage, X-Force, and Hawkeye among others), hasn't really been in anything I can call 'bad' recently. Well, outside of Deadpool Vs. Carnage, which seems to think that Carnage is some type of hillbilly (which he isn't; I've read his first appearance, and some subsequent appearances, and have never seen him characterized that way). Other than that, I've seen nothing awful.
The game was fun, and the movie will be good (this isn't just blind optimism; a draft script was leaked a few years back that I now have and, based on the trailers, it's official and being used for the movie. It's not the exact script they're using, since certain characters/jokes are in the movie that aren't in the script and vice verse. But it has the basic plot and a lot of lines used in the movie).
Let's compare this to someone like Venom, who was everywhere. Venom is not a bad character, but after being over used, he's gotten a bit annoying and the concept has changed from "person who hates Spider-Man and knows his secret identity, can nullify his spider-sense, and has most of his powers" to "former school bully who became a veteran and is now a part of the Guardians of the Galaxy." Yeah, the concept changed, and there were a lot of less than stellar stories.
And I completely agree with you on Wolverine, as he is overused.
Deadpool isn't at the point of either of them yet, and honestly, I like seeing Deadpool. He's a fun and funny charcter, and I prefer seeing more of him than more of Wolverine.
