Are you comparing a 2 hour movie to 50+ hours of anime? Jesus Christ, you are deluded as fuck.
The difference is that a good story/show has to be compelling the whole way through. It simply does not work the way you are describing, like i have said previously, if a story does not draw you in and captivate your mind then it is not good. It needs to interest you at least in the first 25% and if not then it is not worth watching.
There is also a huge difference between fight club and AOT, and the difference is... who knew?? Fight club is good the whole way through, it grips you and forces you to watch. AOT fucks around with shitty characters who are completely socially fucked in the brain and cringey to watch, i started cringing like i had never before when they had those episodes in the training camp. It was not even boredom, its like me and the show were completely incompatible and that i wanted to put it down.
you have to be socially abnormal to like AOT and defend it in this way
