Wow what a ending. Seriously the amount they managed to fit into this episode was astonishing and and contrary to a few I felt it flowed incredibly well without being to rushed. Little things like Klan's Zentradi mecha being replaced with Michele's Skull One were subtle yet very well thought out additions overall. The battle itself and the almost nonstop music really caused this entire episode to come alive for me. In addition I can't give them enough credit for letting characters who died STAY dead unlike some other series with to many Decoy ships laying around.
All and all I would say this series outdid my expectations by miles and I look very forward to the movie assuming its a progression of the story instead of a retelling of the series. Also I think not resolving the love triangle was the best way to end it. This leaves them enough room to finish it up in the movie if they so choose. However beyond that both of the female leads ended up with completely equal footing in the long run so honestly how could they have possibly left Alto to choose one without at least another episode?
Another Note I loved the fact in this series that each of Ranka's/Sheryl's songs during this series and highlighted in the end really tells the story from each girls perspective. You can really tell that each song was written to convey a part of the story and to have all of those pieces put together as a concert for the last couple of episodes couldn't have been done any more perfectly. If you haven't taken the time to read the lyrics and think about what they mean in context to the show I really suggest you do so..
