For me Intermission has one of the highest highs in FF7R, but also some of the more flat sections. The first half is pretty great, with a fun side mission around Fort Condor and an absolute banger of a gameplay section where a Jazz-influenced soundtrack plays the whole way through. The second half is unfortunately less exciting, as the game puts you in literal arenas, from one combat encounter to another combat encounter in a uninspiring manner, but thankfully it has pretty good boss fights. I really liked playing as Yuffie, and I thought the new synchronize mechanics with Sonon is pretty fun to play with, but unfortunately I didn't get to care too much about Sonon, as his story felt pretty by-the-numbers and his personality is only mildly interesting. The overall story is also just meh, felt like filler. The only important part is probably the ending cutscene. At least this doesn't overstay its welcome, at only 5-6 hours in length. It definitely wouldn't be as fun if Yuffie isn't here to carry the whole thing and be the energetic core of it all.
