With the first one, I could pick out specific parts that were omitted for the sake of keeping this feature-length, but I remembered even less about the Female Titan arc than the first one. This one focuses on Eren learning how to control his newfound ability, while his friends begin their time in the Survey Corps.
Now there's even less focus on Eren's friends (minus Mikasa and Armin) in order to focus on the more important story elements present in the second half of season one. It was good, but the story beats you'd usually find in a movie are practically nonexistent here; one scene lasts around 45 minutes, so I'd say that killed the pacing a bit.
It's still a good story, but it's definitely told better in the show. If you have any way to access the show, you should take that and leave this be.
