It has not been great but nowhere near as bad as DCEU in my opinion. Only DCEU film that I thought was good was the first Wonder Woman. Actually Suicide Squad 2 was good. All the rest have been a complete mess capped off recently with The Flash. The new Aquaman looks terrible as well.Marvels - it's not terrible but it's just completely pointless which is worse.
Marvel is dead as soon as it snapped.
Their phase 4 has been on par if not worse than with DC.
Deadpool 3 up next and they will just bring loads of X-Men in buck the trend and get as much money out of this dead horse.
Phase 4 and 5 has had Black Widow, Spider-Man 3, Black Panther 2 and Guardians 3 which I thought were all way better than almost anything DC have done. There has been a lot of trash along the way though and they now have the issue with Jonathan Majors and they seem to be leaning towards changing everything rather than recasting which is madness.
