I still love to rewatch this show, but agree with you 100%. i've seen Bret in other things where his acting was okay. In Reaper he has to react to unforeseen circumstances all the time, and he chooses to wear this slightly annoyed, open-mouthed, confused look every time. It just doesn't work and doesn't make him any more likeable. I think another more charismatic actor like Zachary Levi would've killed in this role.
