i've watched a lot of no reservations when it was on late (and i had cable years ago) that show sucked, i watched a few parts unknown, that sucks too, i've watched him on the taste also, and he sucks there as well.
alton brown is best in his former good eats show, he teaches great, he has great recipes, and he was the ONLY thing that was even tolerable in american iron chef, i was more impressed by alton talking than the pathetic **** the iron chefs or challengers were putting up.
everything else alton brown does, really sucks tho, he did ****ty shows like feasting on asphalt and cutthroat kitchen.
heck the last "physical" cookbook i bought was alton browns gear book, all about kitchen ****, actually a friend "borrowed" it, i don't even know where it is since i threw out every single cookbook/recipes since i move.
