I'm puzzled to say the least on what I just witnessed. I'm not sure if it was well written or not to be honest, pet of me says yes, other half says no, but that last scene, wow...
Very saddened with what happened to Ashi, and I kind of was left with the impression that Jack was left feeling depressed, but retained the meomory of the lady bug metaphor thing.
All in all I have a lot of mixed emotions right now and it might take some time to make a proper judgement.
Regardlesss Samurai Jack is great, and the ride has been amazing. This season gave us Jack's last hurrah, and I'm glad it happened at all.
