The movie is a continuation of the first Progressive SAO - straight into a meaty fight scene right off the bat. The cinematography is so crisp that you won't want to take your eyes off the screen! This combined with the ear-pleasing sound effects made all the attacks from the Kirito gang so satisfying that it's almost like asmr!
...And that's about it :p
Aside from a cute furry being introduced, the movie felt like a copy and paste of an episode from season 1: a plot that was ok at best, a tonne of scenes with lore I didn't really care about (apart from the ones with fanservice), and a villain that looked like a rip off version of the stone boss from kirby. It's understandable why because this series is all about the worldbuilding of Aincrad, but they could've at least developed more engaging characters or designed the floors so they're more memorable and unique like Made in Abyss.
Overall, it's a must watch for lore enjoyers, but it's better off watching the original series if you're in for the nostalgia. But most importantly,
