The Room holds a special place in my heart, and that is entirely due to the memories held while group watching.
The Disaster Artist did a great job at channeling that. Franco is incredible and sometimes it's hard to believe it's really him. I laughed do damn much during this.
Unfortunately, most of the joy I had watching this was because of the scenes from The Room itself. The audience laughing internally brought me back to that group watching experience. That's not a bad thing. Overall the movie is super enjoyable to watch. Cult movies rule.
