I found this movie extremely enjoyable, from the start all the way until the end, it was hilarious!
The beginning of the movie did start off slow, but the gradual progression was good, the story was building up at a good pace.
The ending!! i must say, out of all the movies I've watched so far, this has to be the best ending! It exceeded my expectations, even though a lot of events happened in the end, it did not feel rushed, everything seemed to fit nicely into the story.
The best part of this anime......definitely seeing a future Shinpachi, Kagura, Hijikata, okita and kondo!! But it was the ending that had me excited the most (i replayed it countless of times), i couldn't stop smiling, and i had goose bumps all over!
Also! the sound track and music choice! SpyAir!!! when SpyAir's song-現状ディストラクション started to play!!! Seriously!! i was speechless, and soo excited i could not stop shaking!!
So overall, Gintama: Kanketsu-hen - Yorozuya yo Eien Nare, WAS.AWESOME!!!!!!!!
i highly highly recommend this anime movie! :)
