Why does it feel like when it comes to Live Action TV Shows in Death Battle people choose series that are completely inappropriate?

Don't get me wrong there's plenty of MU's for stuff like Supernatural, Stranger Things, Power Rangers, Kamen Rider, Doctor Who and ever since she made it on the show Buffy The Vampire Slayer but when it comes to it mostly, is people tend to pick sitcoms, (E.G. It's Always Sunny, Friends, The Office, Parks And Recreation etc.) you do realise most of these shows are just guys and girls, you can't scale Dennis Reynolds, he's a regular guy, (He's an evil piece of shit but he's a regular guy,) there's also drama's but with them, people mostly use their wits when it comes to scaling pitting characters known for using their brains as their weapon as opposed to their power, (Like Dexter or Walter White,) point is why do people mostly use grounded tv shows as opposed to TV shows which deal with the supernatural or fantasy elements like Charmed or Vampire Diaries or Once Upon A Time?
