So, after last weeks decent episode we get what is probably the worst episode so far. Metemorpho appears, and is basically written in the stupidest way possible. I don't even care that they changed his interesting origin into a generic lab experiment gone wrong. What annoys me is that he looks like (and for the most part is written like) The Incredible Hulk (although slightly more intelligent). But, thats not the worst part to me. They basically ruined the Metemorpho/Sapphire relationship. Now, I'm no authority on Metemorpho, but I've read a lot with him (a bunch of comics from the various Outsiders series, and the classic Justice League Europe are probably were the most memorable things with him I've read). Do you know one big consistency with his personal life in the comics? His wife, sapphire. In the comics Sapphire doesn't reject him because of his condition. Now, maybe you can point to some comics right when he first appeared where she did, but (before the new 52 atleast) regardless of times they weren't together because of her daddy issues, she never rejected him or stopped loving him. Yes, there were times when they were apart, and rex even had a sort of romantic relationship with crimson fox in JLE, but they still weren't seperated over his condition, and they'd get back together. Heck, they had a child together while he was Metemorpho. But, no, stuff like that is too good for beware the batman. BTB needs to do the most overdone cliche possible in this situation, having the guy love a woman, become a monster, and then have a tragic ending when she rejects him. Its possible that the show might go farther into stupid territory by having him reappear and have Sapphire learn to overcome her prejudice and realise she still loves him. Since that is also the most obvious thing to do, I'm bet it will happen.
As for the rest of the episode, Katana isn't around. She is protecting the annoying doctor from the previous episode a few weeks ago (thankfully off screen, so we don't have to watch that annoying idiot hit on her some more). Stagg ends up being the reason Rex is metemorpho, which I'm actually fine with. The episode just fails when it comes to how rex and sapphire are portrayed. Also, Rex's powers are kind of lame, he turns to liquid once but we never see him as a gas or anything. I'd bet that the stupid cGI causes limitations in what they can make him do, which an actual animated show wouldn't worry about. OVerall, this was just a bad episode.
