I haven't seen either of these but from what I've read about the general story, I think Odenkirk is a decent pick for a film that focuses on a character that is ultimately boring and down on their luck, only to snap one day and find themselves capable of so much more.
I actually really like such stories, there was one I saw not too long ago with Jack Quaid called Novocaine.
I tried to watch Novocaine, but we had a bad feed with the audio out of sync and i never bothered to try to find another one. Do you think it is worth getting?
It's not a bad film at all, but I'd say it's largely forgettable. Maybe try finding it on some streaming service.
