I'm just kinda tired of seeing Jason Momoa doing Jason Momoa things, even as a "different" character.

I hope his Lobo will be restrained by Gunn to keep in-character, and not go off on some speech about road trips, family, and beer/axe-throwing. Like I want his Lobo to be a crude, crass killing machine who enjoys the violence, and not just "biker dad."

Definitely. Plus, he's actually a pretty funny dude so I think he can pull it off. We'll see.
