I continue to be amazed that people can like one show with people running around and fighting in flashy costumes, but not like other shows with people running around and fighting in flashy costumes.
Anyhow, the original point of the Ultra Series is the monsters, not the heroes, or the fights -- the effect of giant monsters upon human civilization was the emphasis of ULTRA Q and this was carried through to the follow up series, ULTRAMAN. So, the hero was just created to fight the monsters and resolve the dilemma or the monster, because the original concept for ULTRAMAN was a benevolent giant monster fighting against malevolent monsters.
When the producers felt that television viewers would have trouble distinguishing between the antagonist and protagonists, they asked Tsuburaya Productions to change the heroic monster into a humanoid alien. The rest, as they say, is history.
If you like ULTRASEVEN X, you might want to check out the original ULTRA SEVEN. I would recommend ULTRAMAN GAIA, which I still consider the best ULTRAMAN show of the Heisei Era (then again, it's close to my heart, since I spent several days and nights on the set of the show), but if you don't dig "giant battles," then stick to KAMEN RIDER.
Then again, if you don't give these other shows a chance (sounds like you've already made up your mind not to like them), how will you ever know?
