In this Lupin III adventure, Lupin must return 6 different treasures that were stolen by Mark Williams... Mark Williams...the actor who plays Mr. Weasley? The center for the Charlotte Hornets? Yeah, sure. Once Lupin returns all of William's ill-gotten gains he will be rewarded with the "Twist Diamond".
This Lupin adventure gives the crew some good villains to go up against. Basically, every member of the gang has their own personal rival to deal with.
The comedy of Lupin returning lost relics as opposed to stealing them is quite amusing.
The movie does feel a bit repetitive, almost like a video game. Lupin must return 6 items escape jail 3 times then he can get the piece of the TriForce and save the princess.
At least he is given a cool cut scene at the end for his troubles. The ending battle is where things come together, and it makes for a pretty entertaining finale.
Much like the MacGuffin of the film, this film is a pretty diamond with a twist.
