I love bad movies with excellent soundtracks. Two stand-outs come to mind:

1) Drive - movie is slow and mediocre but the soundtrack is simply amazing. Kavinsky and Sonic Youth tracks really set a mood!

2) Highlander - acting is atrocious but possibly the best soundtrack every recorded. Unfortunately, today's Queen is like a modern battery, 0% Mercury :-(

But for surround sound bliss smiles, Netflix's "Spectral" was pretty cool and I love bad martial arts movies... House of Flying Daggers has really cool scenes for surround sound systems.
