"@You only say that cause every one on this wiki is a dedicated Phineas and Ferb fan. except me. (facepalm)"

Nope. It's just that the idea that a single show could ruin a huge multibillion dollar company is pretty dumb. Maybe it would make a smidgen more sense if Marvel was just into television animation, but given that they've also delved into comics, movies, toys, etc., it doesn't.

Also, no one outside of Disney has seen Phineas and Ferb: Mission Marvel, so we don't even know if it's bad. For all we know, it could turn out to be great and you could love it.
