The Flash is also a wacky yet heartfelt comedy with a ton of weird gross out humour about an insecure young man with parental issues learning to accept himself. IDK man, if you look at it narratively it seems right up Gunn’s alley - I’m sure he was playing it up for marketing purposes (we know he hated Keaton’s Batman historically and the way the new ending absolutely tanks that character along with Supergirl makes me think he hasn’t changed lol - it’s wild how those two characters just die meaninglessly because they were originally fake out deaths and not actual endings) but there’s so much to that movie in its substance that feels of a piece with Gunn’s own work. It just happens to suck.
Also: Muschietti is not some rando. Why would he ever agree to a humiliating fake hire? That’s a super ****ed up thing to ask a dude who up until that point had done nothing for the studio but make it massive amounts of money.
