Détective Conan: Le Poing de saphir bleu

This movie's nonsensical and over-complicated story is harder to understand in English subtitles than it is in the Japanese that it was written in, uhh mostly due to how it made no attempt at explaining what was going on, when. It has alright animation but the lovey-dovey stuff between Conan's sister's friend and her boyfriend is boring and cringey.

On the other hand, the finale is spectacular to watch and keeps me on edge in my seat the whole time. If you watch the main anime series, you CAN give this one a skip as it has no relevant information or story but if you are bored and really into the series, you can watch this one.
