I've only seen 10 of these 50. Brief comments on each.
50. Glen or Glenda (1953) - Absolutely bizzare. Bela Lugosi as God and plenty of cross dressing. My least favorite Ed Wood.
47. Teenage Zombies (1959) - This one bored me. I saw it fairly recently too, within the past year.
41. Santa Claus Conquers the Martians (1964) - Stone cold bad film classic. A must see for all bad film lovers, as the theme song alone will suck you in.
29. Bride of the Monster (1955) - Bela Lugosi in his last REAL role, a fun movie overall. Great for Tor Johnson fans too!
24. Bela Lugosi Meets a Brooklyn Gorilla (1952) - So shoot me, I love this one. I like the Jerry lewis impersonator better than Jerry Lewis, and Stooge fans, Muriel Landers from SWEET AND HOT is in this one!
23. The Ape (1940) - I love the old Monogram horrors, and this would be one of them. I'm surprised none of the Lugosi Monograms, or the PRC classic THE DEVIL BAT made the list.
19. Creature From The Haunted Sea (1961) - Roger Corman would do so much better after this. This one bored me to tears.
13. The Three Stooges In Orbit (1962) - Typical Derita feature, I don't see how this one stands out from the others for this list.
6. Killer Shrews (1959) - Awesome movie! Those little shrew guys at the end are great!
4. Plan 9 From Outer Space (1959) - Do I really need to comment?
