Thats debatable. Side by side, his Spider-Man films were better than Spider-Man 1, 3 and Amazing Spider-Man 2. Spider-Man 2, Amazing Spiderman and the 2 MCU ones are the 4 best. You decide the order but at least one is in the top 3
The bad X-men films you mention are boring and I dont think there's been a boring MCU film since Thor 2. I think ever film since at the very least has been entertaining on some level
