Like everyone said, it's a really good episode. Love the action, the dialogue, the settings etc. Much was improved from the dreadful second episode.
Am I the only one upset that Raph and Donnie didn't even gave one last glance to Usagi before going through the portal? After all the hardship and bonding.... then they just walked by ignoring him, without any goodbye - like he meant nothing to them???
I wished they all hugged Usagi one last time since this is the last episode of the trilogy (and the last Ciro's TMNT season series).
Oh well, I still love ya Yojimbo.
