Ick... Deadpool. Okay, here's the thing: the character was originally Marvel's attempt to parody a character that was, in and of itself, a parody, having completely failed to get the joke. Obviously, times and writers have changed since then, but the point is I will always be mystified by how popular this character is. I could go on a long comic book tangent, but all you need to know is that in the '90s, ultra-violent dark and gritty characters became popular. DC responded with Lobo, a foul-mouthed, gun-toting, booze-swigging space biker bounty hunter. Yes, it's as ridiculous as it sounds. Yes, some people failed to get the joke (and continue to, based on the amount of serious stories Lobo has since appeared in). But the character became popular because in the '90s everyone was insane. Thus Marvel looked at him, assumed he was for real because he was selling books, and decided to parody him.And thus, that's Deadpool. A joke based on a joke that wasn't even funny the first time around.
Also, I think I have just driven home why us comic book geeks are seldom invited to parties...
