Patlabor 2 is one of my favorite anime films of all time, the crazy variety of projects that Headgear was involved with makes it pretty unique and the content of each entry varies pretty strongly as a result. I can understand not enjoying parts of it because once you get used to one 'flavor' the differences in tone can be unappealing. It's hard to recommend every Patlabor project to different people but the original show is worth watching just to understand the characters, it's not
essential but I found it valuable after having seeing the movies first (anime releases being what they were in the early 00's that's all that was available).
Patlabor 2 in particular is a strong recommendation from me generally, for how well it captures the zeitgeist of Japan in the early Heisei era, at the beginning of their huge economic slump, and tries to articulate some of the anxiety about things like international relations and the legacy of post-WWII policy (I think it even directly anticipates some events that would become major political issues in japan a year after it was released). It's kind of slow for an action movie and they don't get as much use out of characters like Noa and Ohta but it has pretty strong leads in Goto and Nagumo. Spare as they are with it, Patlabor 2 also has one of the best opening credits drops and mecha sequences ever -
It's almost worth checking out just for the score, which boasts some particularly
rich and haunting tracks. I think it's pretty heavily imitated (indeed much of the imagery was shamelessly stolen by some big western directors, not unlike other Oshii films like GITS) but seeing how well its used here makes it easy to forget about the imitators. Obviously I would recommend watching it in the original japanese with subs but with its initial international release dub was the only option, and I have to say I quite like the original english dub by the distributor
Manga Entertainment but my understanding is that this is only available in a low quality mono mix and the new bluray features an all new dub by all new hacks. You can still track it down online and if you're the kind of person who prefers the dub it's one of the (very) few good ones.
The best thing about Patlabor, and other 'creative committee' works by artists/writers/directors of that era is how well it uses all the same elements to make very different products. Some of them are deep, intensely specific works like Patlabor 2 and some of them are just sort of goofy, simple fun (like much of the original OVA series) but none of these things conflict at all. I was never a big fan of the next movie or the live action series but there's enough of what I like in the mix that I still consider myself a Patlabor fan overall.
