I love all the old Universal Monster movies, even the later not-so-great ones.
Same here. I'm not quite so fond of Chaney, though, who strikes me as much more limited a performer than Karloff or even Lugosi - though he was certainly a better Frankenstein's monster than Lugosi was. Okay, so was Glenn Strange.
Lugosi supposedly passed on playing the Monster in the original film, objecting to the make-up. Evidently his career choices were somewhat more limited by the time the fourth or fifth sequel rolled around.
