Decided to see Green Lantern here tonight. My experience was mixed.
The decor and atmosphere is awesome. It's really cheap to see a movie, only $3 (but bring cash), which is great. They have lots of really cool memorabilia to see and I love the neon. The staff was nice and they had a cool arcade area. You could probably spend a good 30 minutes looking around at all of their stuff.
What I didn't love was the quality of the movie. I didn't expect amazing quality because of the price, but sadly the quality was so bad that I couldn't even finish my movie. Seriously, I felt like I was watching Superman from the 80s instead of a 21st century CGI film. But that would have been bearable - it was the sound system that made me walk out to get a refund. It sounded like I was listening to a movie in another room.
Now, I still don't think this is a bad place to see a film - just don't see a high-graphic, action film. I think that this place would get a good audience by playing cult classic films either weekly or monthly. You can hear the old projector, which is a great feature. I would definitely come back to see the classics here.
