I watched the first 3 seasons. It was ok, though the writing / direction of the show often felt disjointed to me, I'm not too surprised it was cancelled. Disjointed as in it'd try and do more adult type bits / to be more serious at times, but then it also had a "Mork" like comedy relief thing with the alien protagonist, doing the stupid sounding pronunciations and so on.
They also tended to pander pretty heavily to topics that are not popular in the states at present, and which are seeing increased pushback in other countries too. Like the muslim girl kid character, who was basically portrayed as a super intelligent loudly outspoken and independent feminist, who had a character foil of an utterly stupid, incompetent cis white boy kid. Or with the adult characters, where almost every cis white character was a fuck up. Town whore was white, town drunk girl was white, trailer park deadbeat dad guy was white, evil assassin doctor was white as was the corrupt doctor he killed -- only remotely positive cis white guy would've been the mayor I think, but he was shown to be basically a sub to his wife (which is why people were so shocked that it was implied he was the dom in the bedroom, it was totally out of step with his normal on-screen persona). The town sheriff was a comic relief black guy, but even he was shown to be incompetent compared to his over-weight white female deputy, and compared to the Indian sheriff from one town over who was "dating down" to be with a "lovable moron". The First Nations people were all portrayed positively / as competent -- the older dad cafe owner / elder who suddenly became a rock star in his old age, the competent town Nurse female lead, the reserve being the 'safe haven', the "good boyfriend/man" that the town drunk pines after is a FN guy, etc.
With that sort of backdrop, and the political climate in the states these days, it's really not too surprising....
