When Marvel goes down the Squirrel Girl path, I'm done with the MCU
If it's true what I read (that Kevin Feige would allow such a ridiculous character to infect the movies), then my following of the MCU will come to a close.
Squirrel Girl is an idiotic character, made more as a lighthearted pun. To treat her like a serious character is mind bending. She uses her powers to "communicate with squirrels" to fight crime. Apparently she's defeated Thanos, which seems like quite a miracle stretch to me and nigh impossible.
Please Kevin, don't go down this road unless you want to permanently damage the MCU.
