It was nowhere near as bad as the reviews suggest. Manny Jacinto was honestly great. The Stranger's helmet design with the metal cables looking like a deranged smile was cool, as was his ability to temporarily disable lightsabers. The new king fu element to the fight scenes was interesting.
Episode 3 was just to make us ask questions that would be answered in episode (I think) 7. They didn’t set this up very well though. It was presented too genuinely, and people didn’t realize we were seeing through the flawed eyes of a child narrator.
