First of all, if you haven't watched the anime yet, do that before watching this or else you won't understand some important plot points in this movie.
Now, if you're reading this I'm assuming it's because you want to know if the movie is worth watching and the answer is, it depends.
Now since I don't know what you particularly liked/disliked from the anime I'll just tell you what I liked and disliked about the film.
Things I liked:
+ Same epic, steampunk, espionage action from the anime
+ The soundtrack (I relistened to LIES & TIES like 8 times now)
+ Some of the expressions in certain scenes are priceless
+ The art is just as good if not better than the anime (Definitely making some wallpapers out of a couple scenes)
Things I disliked:
- It's kinda short at almost an hour long
- Nothing TOO exciting happens. There were moments that had me on edge for sure but, the threats just didn't feel that threatening to me
Random note: Ange does have a different voice actor if anyone feels like she sounds off.
Overall, if you liked the anime, you'll probably enjoy this movie... but not as much as the anime. It's only an hour so you don't have much to lose by watching it.
Maybe my expectations were higher since the release was delayed due to the pandemic, making a long wait even longer, but they did a pretty great job all things considered.
