I didn't realise Mitchells vs Machines was a Miller / Lord joint, and just assumed it was the usual kids cartoon shit netflix pad their lineup with, but yeah, I watched it and can confirm it's pretty entertaining and had a few genuine LOLs from me, even though I kind of actively hated the main protagonist? It reminded me a lot of 'when it was good' earlyish Simpsons in tone, where it had moments of genuine emotion, but managed to undercut it with a gag just before it became shmaltz and that mostly grounded in reality until its really not and nobody blinks setting.
I especially liked the "hello fellow humans" robot pair, and they mined that for some pretty good bits.
