I don't know if I'm alone in this, but I've recently realised that I've been losing interest in the MCU for a while now. I'm not quite sure when it began, but I can attribute it to 2 main reasons:
Firstly, now that the Thanos/Infinity Gauntlet story arc has been concluded, there seems to be a lack of a greater purpose to the adventures of our heroes. And this is important, as I found that the hype for that inevitable final showdown during the Infinity Saga is what allowed me to overlook the glaring mediocrity of films like Ant-Man, Doctor Strange, Homecoming and Captain Marvel as there was a sense that everything was going to build to a final great crescendo. Now however, there's nothing to build towards and this means I'm forced to assess these products entirely on their own merits, which are often minimal.
Secondly, Marvel's refusal to move away from their comfort zone prevents them from telling new or more unusual stories. I hoped that since they had now cashed their $5 billion cheque from IW/EG, this would allow them to do weirder and more bold and experimental stuff. And while they tried this with WandaVision, they did a half-a**ed job and shoe-horned in a cringe-inducing battle for no reason. And Falcon and Winter Soldier's attempts to tackle racism and inequality were as inept as Gamelin's defence of France in 1940. Equally, with the possible exception of Eternals, none of the footage I've seen from the upcoming movies gives me much hope that they are going to break new ground either.
I'll still watch every show and movie because I've come too far to completely ditch this thing, but unless Feige and Co. really pull a rabbit out of a hat and give me something truly great (as opposed to merely "ok"), I fear that I will never again be as hyped for this franchise as I was in the 2012-2019 period.
