AOU actually got A LOT better for me the 2nd time around and I actually think it's a pretty solid movie. IM3 could have been better but my god was Thor 2 bad. It isn't ASM2 bad, but it's definitely the worst of the MCU films, by far imo.
And like I've said time and again, me loving "Batman & Robin" doesn't make it a better film.
The only subjective thing is one's taste.
I can also love TWS but cannot deny the fact that it has problems.
Still a good film, mostly because those problems are small and can be easily ignored.
