What a way to ruin one of the best mangas of all time. What a mess.
The first film was decent although a bit boring, roughly followed the manga.. dragged on some scenes and unnecessarily skipped other important ones, but it is understandable due to limited time. Ending was changed a lot but still recoverable from this error in judgment.
This time however very very little went according to the excellent story in the manga. There was so much potential, but wasted.. the last invasion arc would have made an excellent film, but this was too early for that of course. .but even just some of the finer missions would have been fine. I can think of at least 3 of similar caliber to the ending of the first film.. not exactly sure at which part the plot was in 2011 but still.
Acting was fine, action pretty cool, but the plot was a mess and pure wasted potential. Just read the manga.. and weep.
