A Game of Steves

I keep my criteria for characters simple: if they were replaced by a new guy for an episode—a random Steve who had all the skills required of the character for that episode—how much (if at all) would I care?

NBC's Dracula: "Mr. Grayson had to go...uh...do something...yeah. Steve is in charge at the moment."
Sweet, maybe Steve will better less distractable and better at follow-through.

The Blacklist: "Agent Keene can't be with us this week, but Red's willing to talk to Steve."
Then I'm willing to watch Steve. Can Steve do his job without a master criminal holding his hand and making his position in the organization look like some really fucked-up nepotism?

Hannibal: "Dr. Lecter can't make it this week, but you can talk to Dr. Steve, who brought some suspiciously tasty cookies..."
BOO. NO. GO AWAY, STEVE. GO JOIN TOBIAS IN THE NOBODY-WANTS-TO-BE-YOUR-FRIEND CLUB.

Marvel's Agents of S.H.I.E.L.D.: "Agent Dude can't—"
Alright, bring on the Steve! Let's see what Steve will do! Don't ever leave us, Steve! I'll even bother learning your name!

Breaking Bad: "Steve, let's cook."
NO. I DO NOT TRUST THIS STEVE. SHOOT STEVE.
