Gosh that is a hard question. I absolutely love classic horror movies and Universal's are certainlly the cream of the crop.I love them all but put The Mummy and the whole realm of Kharis movies on the top of my list. I love The Wolf man too,,,so many. I am not as fond of Dracula and Frankenstein movies but still watch them.
My favorite star is Boris Karloff and I have a really nice hard plastic monster statue of Karloff as the mummy.
Lon Chaney Jr. I love as a more pitiful, don't want to be, monster. Larry Talbot breaks my heart.
Bela Lagosi, for me, was best as a partner with Karloff.
