Here's another couple of real stinkers that I enjoyed, back when they came out:
The Stuff - We got a couple of days to relax in some NG barracks during a field problem once, while I was in the Army. This didn't happen very often, so it was a treat. Then, one of the nights, they set up a projector & screen and showed, you guessed it, The Stuff. The movie sucked mightily, but we were all so damned happy to not be out in the woods, in the dark and the rain, that we all thoroughly enjoyed it.
The other one is Time Bandits. No one will ever confuse this one with a masterpiece either, but I loved it when I saw it the first time, in the eighth grade, and I still do.
