3 movies a year is fine alongside 2 shows (most of the GA don´t watch shows either). Which is also reportedly their target output. It became def too much, and agree with the event feeling is gone. Also the quality will most likely be stronger.
Re opening bigger:
Thor and Ant-Man had hype based on previous entries and event factor etc, Vol 3 doesn´have anything of that and is coming of a horrible 2022 and Ant-Man 3. I´m not surprised that the tracking is bad, just surprised of how bad. Many might just wait for D+ or reviews and some might not return ever. Marvel has lost the trust of the audiences. Let´s see if they can gain it back during the next years
