Just saw this and
I loved it!
I dont think you need to be a Pokemon fan to like this movie, as its pretty solid all around. Obviously though, this is a movie for fans by fans. If you have ever loved Pokemon at any point of your life, this is a must see.
I had reservations about the realistic designs, but the animators do a really good job. In motion, the pokemon are appropriately cartoony that the initial uncanny feeling disappears quickly.
All the references/lore is really well crafted into the story. There is definitely a lot of love gone into this. I am very happy, and getting a pokemon card added to the good feelings of nostalgia I had going.
I kinda ruined the plot for myself by watching all the cut scenes of the game, but it's pretty predictable/silly so thats not a huge deal. For those who played the game - it follows the rough story, but definitely improves it in the cinematic sense.
If you are going to rank this compared any of the anime movies... probably in the upper category, based on how you feel on them. I haven't seen every single one, but everything I saw after Spell of the Unown hasnt been that great, imo.
Also the Mr Mime scene was so.... so fucking good. So fucking good.
So yeah, go watch this!!!
