Go-Onger vs Gekiranger was good from start to finish, IMO.
Great to see Mele and Ran once again, as well as providing a link to Geki with Hiroto and Mui, who had trained in Geki when they were little.
Rio still the badass, and everyone else had a good showing; Jan, Retsu, Gou, Ken, Master Shafu, and Miki.
The capper on it all was most definitely Bai and his Mecha battle play by play.
IMHO, one of the better 'vs' I've seen.
