I just completed this series last night and I've gotta say, I enjoyed this series. it's weird, but very fun to watch. among the Hoshikawa siblings, Ken is definitely my favourite. hell, he took down a monster without transforming and even a full grown sized monster in human size. that's just badass!
as for the villains, I really like the one who speaks Kansai Dialect (can't remember his name though), he's so cute and hilarious! :laugh: Shubalie disturbed me during his debut, and to even think he's portrayed by Green Flash's actor?! he has a good singing voice, no doubt, but it was so hard to take him seriously until later on when he finally gets a little more serious.
it was also nice to see Red Mask and Yellow Flash's actors making a cameo appearance.

overall, Fiveman isn't one of the best series in the franchise, but it's definitely a nice get away from all the serious toned series. my only complain is that the finale was too rushed. they defeated Billion, Dorudora and Shubalie without even breaking a sweat! FiveRed never even dueled with Garoa at all either!
