I recently watched this Top 10 video and laughed my ass off. These are all rip-offs Hollywood blockbusters and while nowhere near the quality of the movies they rip-off, they look like fun unintentional comedy that you could probably see for free on the internet (therefore not costing you anything-though I'm sure most of these can be found in $0.50 bins) or from Netflix streaming (those of you who have Netflix know this, but most movies they have for streaming are scraped from the bottom of the barrel). That is if you can stomach bad acting, horrible SFX, and production values that remind me of made for TV movies in the 70s and 80s:

Say what you will about Sunday School Musical, the music is 100X better than the music in the movie it's ripping off.
Oh, for wrestling fans, that is Kevin Nash in Almighty Thor (11:32).
