I just saw the first two episodes of Ultraman Leo, and apparently they're an older release with more primitive subtitles that sometimes don't entirely fit within the superimposed boxes they occupy. They also don't bother to translate the theme song.
Anyway, I'm not sure how I feel about the show yet. It seems to be trying too hard to be Intense and Dramatic in a self-conscious way. But then, I hated the first few Taro episodes, but it quickly got better. Maybe they just need to find their balance. It is an interesting premise, having Dan Moroboshi back on a regular basis as Leo's mentor, but unable to become Ultraseven. I've said before that I appreciate it on those rare cases when someone else is in on the Ultra's secret and they can actually talk about being an Ultra and what that means. Although so far it looks like it's largely just going to be Dan training Gen/Leo in new finisher moves. (And it seems a bit derivative that Leo's finisher is basically a Rider Kick.)
It's a bit weird that the series opens with Dan already living on Earth as the leader of MAC and defending it as Seven until he's sidelined by injury and has to pass the torch to Leo. I guess I can surmise that he decided to come back to defend Earth after Kotaro gave up being Taro. They must've run out of new younger brothers in the Ultra Family. Lucky the Ultras' species seems to have cousins in the Leo constellation.
After today's viewing, I think I'm finally starting to get an idea why Ultras maintain such strict secret identities, even when it seems pointless and counterproductive. First we had Kotaro giving up his link with Taro to show Kenichi that humans should rely on themselves. Then we have Dan telling Gen (who, like him, is a pure Ultra in human disguise rather than a bonded human host) that they have to live as humans while they're on Earth and mustn't use their alien powers in their human roles. I guess it's kind of an Ultra Prime Directive -- don't interfere except in the gravest emergencies, let humans solve problems using human abilities and technologies as much as possible, so that they don't become dependent on godlike aliens. It just so happens that the gravest emergencies crop up about once a week.
