Saw it and can definitely see why it will be a loser for MCU. All of the acting was fine, but the story line left a considerable amount to be desired.
IMHO MCU has been in decline with regard to film quality when they released Black Panther. Infinity Wars, End Game, Captain Marvel, Dead Pool 2, and even Guardians of the Galaxy 2 were all poorly written and lacked the ingenuity that the story line deserved. DP2 was a rehash of the original and GotG2 displayed none of the hallmarks that made the original a classic.
“Saw it and can definitely see why it will be a loser for MCU”
It’s not a part of the MCU. None of the X-Men movies have been, nor have the Fantastic Four or Deadpool movies.
The next X-Men movie will be the first under the MCU banner.
