AOT is a good story with good characters and good animations. The major issue is one of pace. The first 3 seasons are a major drag fest. The first major battle didn't have to be 9 episodes and there was only one arc in the 1st season with powering through. Regarding the first 3 seasons, the last half of season 1 and the last 2 episodes of season 3 are worth the watch. Season 4 is the best season overall mainly because of MAPPA overseeing the release as opposed to WIT Studio. If you have pacing issues, watch the compilation movies.
