In My Opinion:
I hope that after this next crossover, Film Brain goes back to normal reviews. I mean, crossovers are okay, especially if the two (or more) reviewers have chemistry that can drive the review. For example, his crossover with Rap Critic on Big Momma's Like Father, Like Son was really funny because the two had good chemistry. Rap Critic was a good straight man and Film Brain was the loveable goofball. His crossover with Linkara in 2010 was terrific for the same reasons, as was his crossover with Welshy and Cinema Snob, Todd, and even Lupa.
Sadly, his recent crossover with Oancitizen and the one with JesuOtaku did not work. It doesn't help when they review a movie that's incredibly boring and stagnant so that they have to look hard for things to point out and rip on. Sucker Punch was horribly tedious, and on top of that, Film Brain and JesuOtaku did not make a good team. JO was flat out mean and FB was annoyingly childish and it continued in a cliche that's thankfully being phased out wherein two reviewers are forced to review a movie and one of them hates the situation like hell. With Rap Critic and Film Brain, they meet up at the start and agree to go review a movie. Simple, straightforward. Plus, JO and FB had no chemistry and did not work as a reviewing team and as a result, the Sucker Punch review is, to me, quite unwatchable.
Film Brain and Oancitizen's crossover didn't work because the movie was boring, and the two just didn't play off each other very well, hence the review was boring. Both are fantastic reviewers on their own, but together, it just didn't work.
So Film Brain, I hope the upcoming crossover will be the last one for a while, because I and so many of your other fans really enjoy your traditional Bad Movie Beatdowns, and if you want to do another crossover, how about The Nostalgia Critic or Phelous, or Lindsay? I think you would play off of them really well, and you don't have to wait until you're in the same room, just do like they usually do and cut back and forth.
