To be fair I will probably give Bland Widow a miss, so I can't say I will be seeing every MCU film post Endgame.
Any way I think the reason the MCU was the only Cinematic universe that actual succeeded was partially because they had the benefit of being the first and thus the novelty of it all made it easier to overlook the problems, because it actualy did take them a while to get it right. By the time the novelty wore off they had more less got it down to science, so that didn't end being a problem for them. Every other Cinematic universe though dosn't have the benefit of said novelty and thus the audience are less patient with their struggles to find their voice.
