If this thread had come out a couple months ago, I'd say that Hurricanger had the best team chemistry out of all the shows that started with only three members, but then Go-Busters started and that show has been impressing me something fierce on all accounts, including the team dynamic, so there you go.
More generally though, Hurricanger is in my estimation a somewhat above-average season, with the better parts of it coming through in the little details rather then anything about the big picture. Oh, and Tenrai Sepunjin, the final mecha that is the combination of all six mecha, was amazing and really well put together, one of the better final combine everything mecha I've seen.
