Over the last two days:
[OT] Kamen Rider Build #49 (END)
[GUIS/SXIG] Chikyu Sentai Fiveman #43-48 (END)
Fiveman is often named as one of the lesser Sentai seasons, and I can see why. A lot of episodes are just plain silly, even by tokusatsu standards, and there's a lot that's rehashed from previous seasons. I can't deny I was quite bored at times, but I can't completely right it off either; There were some really cool stunt sequences and occasionally some good model work, and (like Bioman IMO) the final arc is better than everything that came before it, so it goes out on a high.
Out of the the 3 Chosishin series I think Justiraiser was the best one with Sazer X being the worst. It did have some pretty good mecha design's thou with Shark leaguer being the biggest stand out.
I will probably get around to watching Justirisers eventually, but with everything else out there I can't imagine it happening for at least a year or so.
I've had Juspion, Solbrain and Return of Ultraman all sitting on my hard drive for months now, so I'm long overdue to dive into one of them and cut down this backlog (especially as Juspion is coming out next year and I want to know if it's good enough to be worth getting a region 0 player, importing the set etc). But I must admit part of me would rather keep this Sentai train going and watch Goranger now that it's completely subbed.
