Extremely unpopular opinion, but I think the problem with most mecha anime is, ironically enough, there's not enough robots. They'll often spend 90% of an episode trying to resolve drama or talking about things, and maybe if you're lucky they'll have a robot fight at some point. Betterman was REALLY guilty with this. Half the episode felt like you were reading a CTRL+ALT+DELETE combat, and you rarely ever saw the Kakuseijin or Tyran.

Sometimes you just wanna see robots duke it out, without needing context. Like a barfight between giant robots.
