[Blade Raider]

Depends on the show and timing (and my mood, honestly). Generally, in the early episodes, I look for characters, both heroes and villains. Regardless of plot, if I'm going to sit through 50-ish episodes of a show, I want characters I enjoy watching. That is the foundation of a good show, really. Enjoyable characters will carry the show for a while, long enough to add more heroes/villains (just don't overdo it), and then the added characters can carry the show until around episode 30. Around that time is when I get really anxious for plot and/or twists that will carry the series through the end. I like some kind of subplots going on before then, like villain infighting or a quest for some power up. Something to tell me there's more going on, but it's not the focus yet.

So basically, first half of the show is more about characters and second half is more about the plot and I like a good bridging subplot in the middle.
