Megaranger!

Uneventful episode, but there was one thing that I liked, and that was Nezi Red's screaming and flailing over why he can't kill Mega Red, despite literally standing on top of a beaten Mega Red. I don't know why I enjoyed that particular scene, but that one track mindset actually makes for an interesting villain.
"What do you mean? It makes them more dull. They only want one goal, and nothing else."
It's a simple character turned more complex just by thinking about them.
A character like Guirel, for example, wants to advance and rule, and he'll plot, lie, and betray anyone to achieve that goal. In a sense, it makes him predictable (From the audiences' view) because you know his plans will always have some sort of fine print to further his own goals.
Nezi Red wants to kill Mega Red. It's a goal that doesn't have wall after wall to achieve. However, what makes it more interesting is that he's clearly sentient. He's not a drone, and this episode proved it with his screaming over his forced retreat preventing him from getting the kill.
A simple story arc could be Mega Red pretending to die, but not by Nezi Red's hands. It could give something of an identity crisis to the character.

Oh well. As it stands, what makes them interesting as characters is what we're not told about them. The mystery over everything else. And since they were introduced so late into the game, while they weight of their threat is felt, they're not powerful as characters alone.
