I generally think most battle Shonen works best in movie form. Establish the stakes, establish your broad characters, they fight, good guys win, and everyone goes home happy. If you can do it in under two hours I won't feel like I wasted my time, and this movie accomplished exactly that. Does it make sense....sure..... I do fully believe Seto Kaiba would invent time travel as a means to satiate his own ego after the end of the original series. Do I care about the villains plan? Their motivations? Their name? Nope, I just needed them to stand there, twirl their mustaches and laugh outrageously asthey detail how they're going to take over the world using the power of their millennium box? Cube? Macguffin that I don't care about?

The fan service was the exact amount that I needed to have a good time as someone who hadn't engaged with the franchise in probably fifteen years, other than abridged.

However, if you don't have any nostalgia for Yu Gi Oh, avoid this like a plague. Its kind of a piece of shit.
