Nah, there's definitely an element of fatigue. I used to watch superhero movies pretty religiously, even renting movies I missed before watching the new avengers flick. I even went to see Infinity War day one, and it was such a shock that I remember sitting in the car in silence on the way home (though I did cue up Snow in Summer from the NieR soundtrack... IYKYK). After Endgame, though... It was like a switch flipped. I had just watched this big, amazing payoff film that celebrated nearly a decade of cinema, had highs and lows, I watched actors and characters I had followed for years giving their goodbyes... It was a big, emotional moment, and the feeling I had afterwards was like the end of Thanksgiving dinner where you've finished your slice of pie and are enjoying the warm and fuzzy feelings. In other words, I was full.
So when Marvel kept producing more movies at the same pace as before, it was like the end of Thanksgiving dinner, except now the host is starting to bring out another pie and putting a slice in front of me, and now I'm side-eyeing it and trying to find a polite excuse to say no and go the fuck home.
The Phoenix Wright trilogy--the first three original GBA games/DS re-releases. They set up and develop so many arcs that pay off both within each game and across the entire trilogy. I would even go so far as to say that Phoenix Wright 3 is one of the best visual novel games of all time.
