Geki probably could have been told in 13 episodes, it had its moments, but its definitely not a show that held my interest. Watching it a second time through feels more like a chore than something I can enjoy. Even though there are a lot of things I do like about it.
Hate Go-Onger all you like, but I really like it, I can go back and watch just about any episode and still enjoy it as much as the first time I saw it, same for Boukenger, Dekaranger, Timeranger, and any other Toku series I've liked. Shinkenger could possibly be up there, depends on how the next 5-10 episodes go.
Like I said, I'm pretty easy please, If its entertaining, has characters and stories that hold my interest I'm there.
For me it's been a pretty good stretch because I've really not found a show I've really disliked on the Toku side of things. PR on the other hand, I'm just happy both RPM and KRDK have been great series so far.
