Exposition

"Show, don't tell" is a very common phrase that every type of writer in the fricking universe has heard. A very basic bitch of a fundamental, you want to offer the audience a visual of what the hell's going on. Exposition by itself is NOT a bad thing. Many acclaimed writers have used it, however BAD exposition is awkward, takes away from the story, and just makes it worse. MUGEN DUDE has a fucking massive amount of this. Often you'll find character saying shit we already know, have fuck tons of text explaining shit nobody cares about and that ultimately, has no effect on the story. Speaking of...

Shit no one cares about
"Tell, don't show" seems to be Alex's motto, as there's a lot of really bad exposition in his fanfiction. The original's episode 3.5 was basically exposition the episode. Having a whole episode dedicated to explaining the universe is not a bad thing. However most of the info is practically useless. Many characters will often flat out say how they're feeling, things that you can already fucking tell or something about the universe never foreshadowed. The character of Original TLR is pretty much this problem personified.
