...but if you're watching this because you just wanted to see the main actor on screen 98% of the time being a boss, or just because you want to fangirl/boy over the attractive actors you liked in S01, you should tap out.
As someone who has no particular affinity to anyone in this show (except for Lee Si young because the actress is amazing and so is her character), as I usually do, I wanna' cover the good, bad and ugly of this season's offering;

THE GOOD:
- High action and developing horror and drama right out the gate, and it stayed that way for at least 80% of the season, no holds barred, humanity at their best and worse, chaos and entropy and monsters abound. S01 covered the basics, which, great, it let us get attached to the respective characters as one must in order to continue watching something, but would I want to watch a whole other season of the same characters doing the same shit? No thank you. S02 brought the broader scale of shit hitting the fan and escalating, we saw the reality of a dystopian world crawling with monsters really impact everyone. The fact that so many people are complaining about S02 baffles me. To viewers griping about deaths of MC's; come on! People would DIE, whether they are popular, good, bad, kids, attractive or ugly. So many shows from other countries based in violent, supernatural horror worlds, cling to their full set of MC's (*coughs* The Walking Dead) to the point where it's eye rolling. I don't want ALL the main characters to survive and be besties, that's BS, because it wouldn't happen that way. Sweet Home was merciless on this front, I loved it (PS: I would have been super mad if Yi Kyung died tbh but I would've gotten over it and still watched S03)
- The story unfolded on a bigger scale, which gripped my interest immediately. They did a good job of showing the peak of escalation and loss the beginning and then the time skip was just long enough to show the bare minimum of what was salvageable, and how unstable it all was.
- They introduced many new characters living in the stadium, most of which I assume will come in handy in S03 for deaths and monsterization. Useful trick to stop killing off your entire main cast in your final seasons. They also set up old characters and some new characters to really shake things up in S03 with gruesome comebacks and they highlighted them well too.
- The acting is ON POINT for everyone. Seriously, everyone brought their A game.
- Lots of foreshadowing, probably the groundwork for S03 plot twists.
- The clever broadness of monster capabilities being based on their desires and hates also really leaves a lot to be explored.
- Hyun Su going dark under his monster because of pain is the PERFECT precursor to when he breaks out of that lapse. I am keen to see him take back control and throw down.

THE BAD:
- The thirstiness of the female characters in Asian shows. I don't think this is a Sweet Home problem, I'm not sure if it's a culture thing, but characters like the chief's daughter and that loopy chick with the old man, that borderline stalker sexual harassment vibe they give off is ick, I could really do without that. What's wrong with them just being flirtatious instead of obsessed with the singlemindedness of a small brained creature in need of love and marriage? Hard no.
- I think the writers are trying to make Eun Yoo likeable, which, PFFFFFT ????? no. just no. They already made her the most dislikeable wench possible in S01, uh, what do they think changed? Nothing, she could have died in S01 and I would have forgotten her, like I forgot her brother.
- The monster CGI is...passable-ish. But I wasn't expecting it to blow my mind so it's whatever.
- The survivors looked pretty healthy despite living underground and eating minimal rations and barely going out (if at all for some of them). So that was a ball dropped, but it was small ball.

The UGLY:
- If S03 involves any romance, it's gonna be a gross joke. There is no reason for it and zero sexual chemistry with literally anyone in the show so far. Even Uen Yoo and the nice soldier guy don't bring those vibes enough for it to come to fruition. So, that would be ugly. I hope they skip right over that shit idea. I want nothing less than to see any of these characters kiss or touch each other, ever. Not only because it's unnecessary story wise, but also because everything is unhygienic and filthy and it would be high key disgusting to see any physical sexual contact of even the barest kind when I could barely stop thinking of how badly everyone must stink in every way.

THE HIGHLIGHTS
None in particular, the show had too many moving parts for any big, standalone moments, but I'd say the acting was for sure a really great thing for this season.

Overall, I enjoyed it just as much as S01, I have no complaints and I am keen for S03.
