I've only seen basically the highlight reels of The Room.
This was very good, James Franco does a bang up job. It's very funny. The movie takes it's time getting started, but it needs that to establish these characters, so you actually feel something for this weird dude who is just totally alien in so many ways.
Also, the side by side comparison of what they shot, and what happened in The Room, was really spooky and eerie, seeing franco and Wisseu side by side.
