Super bizarre as a movie. Probably great for people who watched both Decade and W, but as someone watching this to round out my W experience, this was just really weird. I may be biased, but I think the W parts are more understandable even if you haven't seen W, but the Decade parts were really confusing with no knowledge of that show.

The tone shifts are really crazy, as the W section (while it has some emotion to it) is overall more lighthearted and slapstick, and the Decade section is split between edgy protagonist angst and ridiculously campy villain scenes. I want to reiterate that, at the point where the storylines converge, Decade has been going through deep discussions about his moral compass and struggle to be seen and is facing down a giant nazi airship, whereas W is chasing a character who has turned into a tire and is making onomatopeia sounds as he rolls down the highway.

Overall, though I ended up fast-forwarding through some of the Decade parts, I did enjoy the W bits, and the rating is primarily for the fact that I liked the Shoutarou/Philip backstory and that Skull is really really cool.
