I've never made a secret about it- movies about blobs and stuff scare me. Heck, even The Unknown Terror got me as a kid I know it's weird, but things like that could exist at the bottom of some lake or swamp. I read a story about years ago about a similar thing that came from the bottom of the ocean and it was just as scary.
So here's the trailer to the original and still best Blob movie, though I enjoyed the sequel for what it was. The remake started out good, but ended stupidly. I hear there is going to be another remake. Beware that blob.
