>>6119226Geez, there are a lot of good ones to recommend.
Fourze is a great place to start. W is another good one. Drive is a little bit odd and takes a little while to get into gear, but it ends satisfyingly. Gaim is a weird series that is pretty cool (it's written by Gen Urobuchi, who also wrote Magica Madoka, so there are a ton of similarities between the two works), worth watching but also a far bit different than most usual KR series. The current series, Ex-Aid, has been enjoyable so far, kind of a cross between Drive and Gaim. Amazon and Amazons are both great. The original is absolutely worth checking out, but last I checked only the first 40 or so eps have been subbed. My personal favorites are Black and Kuuga.
Honestly, the suggestion to base it off a costume isn't a joke.
The only series really to avoid is Wizard, Ghost, Kiva, and Decade. Wizard's plot stalls around ep 10 and never goes anywhere (but it does have good fight scenes). Kiva has a cool costume but other than that I couldn't like it. Decade isn't terrible, but since the gimmick is revisiting alternate versions of the previous series, it's probably better to just watch the original versions that base anything on alternate universes. Ghost is absolutely the worst.
