binged through the season, definitely a ton of flaws and "wtf?" but in binge mode i think you sorta can ignore the dumb shit and enjoy all the alien shit.  Episode 5 was the tits, the alien fan-made movie we wanted the last few years but never got.
I definitely understand why people hate the finale, it felt like a mid season cliffhanger instead of a season end.  too many people with plot armor.
hopefully they can build and make a better season 2 but likely s2 will be worse, its just the way these things have gone for most new shows.  If they move to Weyland Yutani land it could be interesting.
if you're on the fence just view it as a mediocre, expensive budget weird fan TV show and i think you can mostly enjoy it, especially on a binge, especially around Halloween.
Can't say I give a shit about a single character, although I did enjoy Morrow, boy Kavalier (for being such a smug douchebag retard), Robot Raylan, and of course all the aliens.  That was the real highlight, it was pretty awesome seeing 5 different alien species and wish we had way more of that.  octoeye rules.  I don't watch much horror and the show was really, really tense so many times although by the end the xenomorph felt too neutered, like a pet dog or some shit.
