As much as TGWTG mastered the angry reviewer genre, they certainly have acquired some hacks over the years. If I had to rate the Top 3 weakest hosts on the site, it would be Angry Joe (dolt), the Blockbuster Buster (fame-hound), and Mr. Buck. There is no point to these shows, other than the self-glorification of the hosts.
The best you can say for BMB is that Matt typically eschews sketch comedy, and he actually knows his movie-making shit. Unfortunately, Film Brain really has no personality or uniqueness of his own: a self-admitted copy of the Nostalgia Critic (himself an over-the-hill parody these days), he acts snide and sarcastic toward everything, moving his head around a lot as he does. No jokes or levity in-between.
Perhaps the most annoying aspect about Matt is his clumsy padding out of each review. It's obvious when he's running long on time: he'll start acting self-righteous or offended like Helen Lovejoy. This could be anything, from a Hollywood explosive which doesn't damage the set to his liking (where's the demolitions degree, Matt?), or allusions (not on-screen depictions, merely a mention) to child killings on the part of the lead villain. "OH REAL TASTEFUL!", he moans. Either he's finding reasons to get angry, or he needs to develop a thicker skin. He's not reviewing arthouse cinema here, it's mostly action schlock; so what's with the moral outrage?
Anyway, he's a terrible reviewer and hasn't evolved one inch since he began all those years ago.
