Sweet Home Season 2 misses the mark completely.
Random characters are being introduced at every moment. Previously well-invested characters are being killed off or quickly forgotten. We take the perspective of 10 different characters, a few of whom are well remembered, some, known yet unmemorable, and many, entirely new and forgettable. These are all in the midst of 5 completely different yet irrelevant plotlines taking place simultaneously. If that wasn't bizarre enough, many of the exchange and dialogue between the characters do not make sense, yet all the characters seem to perfectly understand another (almost as if they all telepathically understood what the writer desired!).
Notwithstanding these errors, the show also does a complete 180 of its portrayal of the monsters in Season 1 to feature them as misunderstood, unintentionally violent creatures, which still retain their human souls entrenched deep within their anatomy, somewhere. Where exactly? No idea. But we know they still hold onto their humanity!
The show, then, passes guilt unto the survivors and forcefully tries to garner sympathy among viewers by making the monsters resemble harmless animals, infants, children, or parents. No, no it is not the monsters that are causing mass destruction and deaths that we determine to be evil, it is those pesky, paranoid humans who are the true evil incarnate as they resort to wanton violence (the overused and banal "humanity is the true evil" trope rears its ugly head again).
Season 1's writing was not spectacular either, but it at least got the job done; on the other hand, the quality of writing in Season 2 takes a steep nosedive. I have no idea what happened here, but if someone claimed a random intern took over the writing department, I'd believe him without hesitation. Fortunately, there a lot of random action sequences and CGI interspliced in the muddled storyline to distract the angry viewer from trying to understand this nonsensical story, but they still are not enough to salvage this mess of a show.
