Patrick Stewart, well... if you're looking for "not hammy", you'll get it. Some critics and amateurs (like those dumbshits at Redlettermedia) ended up disappointed that he wasn't more overtly menacing, which just means they missed that that's the entire point. It's more of an acting showcase for the late Anton Yelchin, who tragically died in a senseless automobile accident shortly after the movie came out. Previously I'd only liked him in Only Lovers Left Alive (and Charlie Bartlett is one of the worst movies of the 00s), but apparently he was just getting good.
Do I hate Tarantino? I hate what he represents, I guess. I think he's only got 2 good movies, the rest have a scene or a performance I enjoy, but the rest of them suck. I mean... can YOU cite one memorable line of dialogue he's written since the onset of the 21st century? I can't! Mostly I just hate that I wasted so much of my 20s defending him to skeptics who were probably right all along.
Really, what was Axl supposed to do? I mean, other than not dress up in those dopey 1990 threads in the first place. The guy was clear in over his head from day one, I don't think there's any era where he would've handled fame gracefully.
