So, quite a while ago (over a year ago), I watched Generator Gawl, which was one I had always wanted to watch and never gotten around to.
The premise was quite fascinating and had a lot of potential, and despite some paradoxes and plot holes was very interesting--but unfortunately, the whole first half of the series was monster-of-the-week fare with no plot development at all, and that was a bit painful to get through. Overall, though, the second half made it worthwhile, and I am glad I watched it. (And no matter what anyone says, that intro song is simply awesome.)
Recently, I just started watching the original Patlabor TV series (episodes 1-4).
Although I'm not very far into it yet, I am really enjoying it. In contrast to Generator Gawl, although the first 4 episodes each have a 1-episode plot arc, it's a different thing each time:
Episode 1 is about stopping an attempted theft of a labor robot.
Episode 2 is a tournament to decide positions within the squad.
Episode 3 shows viewers what the daily lives of the characters are like and is about some shenanigans which they have to cover up before the boss finds out what a mess they made.
Episode 4 is about going to capture a monster that somebody reported to the police.
I'm also enjoying the little cultural tidbits like the characters composing haiku and the green meadows song, as well as the humor of the series. (For example, I love the captain's deadpan reaction to everything.)
