As for Deadpool saving the MCU, it will take more than 1 film to save the Mcu. They need to cancel/trim down their annual originals coming straight to Disney+. When it comes to future movies, the success of Deadpool wouldn't guarantee that Captain America, Fantastic 4, Thunderbolts and Blade wouldn't flop in 2025. Those need to be good, marketed well and released at the right time. Dumping them all in 2025, is not wise imo. Who knows if Avengers 5 and 6 aren't critical failure, etc.
