>>858Oh dude if you like very comfy Patlabor you're doing yourself an immense disservice by not watching the TV show + 2nd OVA, they're peak comfy. Also yeah, production order > anything else, as always. I fell into the same trap too at first though, I don't blame you. People really tout the "separate continuity" thing a lot with Patlabor, but it seriously doesn't matter. OVA1 -> Movie 1 -> TV -> OVA2 -> Movie 2 is the best way to watch.
Also the lake monster + academy episodes are just goofy genre parodies, the former more specifically being a spoof of godzilla. There's nothing really to "get" about them, it's just the characters having fun in a famous movie scenario.
