Dave Franco is there just because he is a bad actor?

Rating: 7/10 (20 January 2019)

James Franco did such a good job, but can't tell if Dave is there because he is another disaster artist or he is just the brother of James?
If the reason is the 1st one, then this makes sense. Just can't stand the way he cannot act and control his cracking teenage voice
What do you want me to tell about the movie? Not much to tell
