You know what? I liked it. I went into the theatre biased by reviews that it would royally suck and I came out having enjoyed it and totally fallen in love with a character I didn't think I'd like.

I can understand where those expecting a certain something from the animation were disappointed (as the scenery was beautiful, but the character movements left something to be desired and I don't think some characters looked enough like the actors that portrayed them while others were very good translations into a drawn media, non-motionwise) and I can understand how canon purists are annoyed at it as they were with 1-3 (as there are characters and plot elements here that will need to be taken care of quite specifically before the end of the TV show run and I too was a little "ugh, really?" when I first heard about the additions).

I think the animation could have been better and I don't think it will ever be epic as 4-6 obviously are, but I think it's thoroughly enjoyable and it recaptures the humor we see in 4-6, which was something I really loved about it. I think the crucial element of my enjoyment was character dynamics, rather than animation itself or specific plot, because there was definitely good back and forth in this movie.
