I watched Creature From the Haunted Sea and it was better PQ than I was expecting considering the disclaimer they put up. They showed some of the restoration work they did as an extra and it's pretty amazing. The film itself is very low tier. There is a running joke with two of the characters that make animal sounds which I can't imagine was funny even back in 1961. The creature is about as hilarious as it gets. It is a Roger Corman film and at just barely over an hour it goes by quick enough.
