I'm not gonna do a full review, but I will say that that episode was so... not good. And JF was off to such a good start.
Everything in this ep seemed so forced and contrived, like Theo being such a master at flipping the pizzas when he was so terrible at it a few episodes ago. And I get that even the most confident rangers doubt themselves at times, but they really turned Theo into a whiny little bitch. Considering that he's supposedluy such a perfectionist, it would've been a MUCH better plot had he tried to train harder to beat the monster next time instead of giving up on the world like that. Especially since he told Casey not to get to down about losing just two episodes ago. I mean, really, did the writers just forget about that?
