The Stuff! (which is basically the same stuff as The Blob, but comes in different colors.)
With a title like "The Stuff" you know you shouldn't be expecting much in the form of a story, but still, you won't be bored for a second. The Stuff won't let you.
The film is stuffed with faces you've seen before in all kinds of weird-ass 80s movies, but don't remember the names of. Most importantly though, it was written and directed by Larry Cohen, and as always, his name on the poster is a sure sign of atmospheric grittiness, wonderful pacing and pure entertainment.
This is another beer drinking movie, but I would also recommend you make some popcorn before pushing play, so that you have something to stuff that big mouth with, while you're watching this stuff.
