I've watched all 4 movies (no shame) and since I didn't write a review for TSD 2... I'm here for the finale.
Ok, well if you're looking for something that will mind f*** the s*** outta you then LOOK NO FURTHER! I will openly say Part 1 was my fav. This wasn't really "bad" it just threw unnecessary amounts of unnecessary stuff everywhere. The plot holes were endless then would suddenly all be solved by these bouts of AH-HA! Moments. If you've made it this far in this series, it's still not for the faint heart.
I wanna say Ruka is bae but maybe just bae... adjacent lol
and YES... you have to watch them in order.
Enjoy...
