I think he's a character with a lot of potential, but don't like how slapstick Deadpool has become. I think he's been mishandled lately.
If I ever end up working for Marvel, I'd like to pitch a more serious Deadpool series - still with dark humor and very occasional breaking of the fourth wall (think "Funny Games" if you've seen that movie) - where he is de-powered by AIM or something and forced to work for them. Thus, the body armor.
The bad guys fix his face and 'Pool stops hearing voices after his healing factor is dampened... but he starts hearing things again after a few knocks to the head. He'd team up with Machine Man and fight guys like MODOK.
