The Void- The worst kind of movie, one that almost gets everything right. The idea is there, the visuals, the setting etc. It's all there it just doesn't come together. Bad script, casting, acting, pacing, editing and cinematography while not quite ruining it detract just enough from all of it's strengths to make it frustrating. I will say that some (not all) of the practical effects and there are a lot are excellent but just like everythignelse there is enough wrong to keep them from being great. The creature design in particular is super awkward and at times cheap looking.
Anyways, it's about a group of people stuck in a rural hospital under attack by a cult who discover that beneath the hospital is essentially a portal to another dimension and the cult leader is trying to open it to let out Hellraiser/Lovecraftian beings. I would still recommend this despite it many flaws as enough of it is enjoyable or just cool/weird enough to make it mostly worthwhile.
The Velvet Underground- I actually couldn't finish this one, had to shut it off with about 40 min. left. The constant noise and the way that it's edited with split screen montages is a perfect recipe for a major headache. Also from what I did see this would have much better off if it had focused more on Lou Reed and less on the whole NYC mid 60s/Warhol scene. It took a good half an hour to even get to formation of the band.
