From my perspective, OBAA is a farce, a lot more subtle than what the Coen Brothers would create but a farce nonetheless. For evidence of this, look no further than the character of Sensei Sergio, he’s straight out of a comic book. Another cue is the ridiculous “I was raped” excuse that Lockjaw gives for having carnally known Perdifia.
For the movie to work I think it’s best to focus on the differences between the genuinely committed (Willa, Sergio, Avanti) and the fakers (Perdifia, Bob, Lockjaw, Tim Smith). Think about what Willa says to Lockjaw when she first meets him: “You're wearing lifts in your shoes. You’re wearing a girdle.” She sees right away that he’s fake, that he’s just acting, he’s not committed to his cause, he’s doing all this for convenience. Another cue about Lockjaw’s actual state of mind are the tears in his eyes when he realizes he’s going to have to kill Willa, he’s not an actual white supremacist, he’s just cosplaying, likely because he can benefit from doing so. Tim Smith, too, he’s this tough guy playing assassin who manages to leave Lockjaw alive and then gets himself ambushed and shot dead by a teenage girl. Just a poser, he is. And Bob, God bless him, the only thing he manages to do in the entire movie is get Sensei Sergio arrested.
There’s one shot I love which happens immediately after Willa escapes and is reunited with Bob. It’s a tight shot of Bob in profile, where he actually looks not crazy for the first time since Perdifia walks out, you’re thinking that he’s a new man with a new lease on life and then the camera slowly zooms out and you see him with a beer and a joint, no growth there whatsoever. I loved that shot.
