Overall: Fun but mostly filler
I think I can honestly say LvP well subverted my expectations. I really did expect the two teams to eventually have to team up, but I also expected them to work out who the Lupins were sooner. However, apparently all you need to avoid being caught by the police is 10% of your face covered.
My favourite in the series had also immediately been Zamigo, and in LvP's need to subvert my expectations they decided to make him barely in the show until the final act despite the fact he was the direct cause of the plot.
LvP's writing is messy and basically the entire middle is filler that could of been spent better. I did enjoy the show though and at least the filler was fun so I still enjoyed watching it when the plot wasn't advancing.
I ultimately recommend LvP as long as you can deal with senseless filler and Sakuya's existence. It's a good show otherwise.
