I don’t like his material after “The Room”, it feels way too unauthentic and forced self-parody to me, even if he manages to make it funny bad again (but not really same tone as the movie).

In “The Room” he’s definitely being his authentic self trying to make what his idea of “good” movie was, you can read about it in Greg Sestero’s (Mark in the movie) and Tom Bissell book “The Disaster Artist” if you doubt with what intention he made the movie. Or even listen to it in audiobok form, Greg does amazing impression of Tommy and sheds lots of background info on their history and how the movie came to be
