yeah i love it too. i thought the last arc was too serious. i always thought i was very particular on anime/drama having a good plot and so when the last arc was gonna be all plot i was excited but then i realize gintama is very odd (for me) and that hte best parts are the lame slice of life ridiculousness.
one of the best moments for me was when the king lost his underwear or something that was killer.
but the live action was able to replicate the benizakura arc movie fantastically. very rare that anime can be successfully copied to drama
