I really like the first season of Teen Wolf. I liked its characters, the interactions, the conflicts, and atmosphere. When people started getting killed, I liked how the town had a curfew. Its little details like that which are so absent this season.
For one thing so many of the characters have regressed to previous personalities. Allison's dad now hates werewolves again, Derek is a violent vigilante, Lydia remains oblivious to Stiles advances.It makes fans feel like the first season finale was ultimately ignored and stripped to only make new conflicts.
A new monster has appeared and it totally doesn't look like it was ripped from the new Spiderman movie, not. The monster mystery isn't as compelling as the "Who is the Alpha?" was from the previous season. There are only two suspects who could be the Kamina so there was an obvious double fake out. The Kamina is very inconsistent about how powerful as it easily incapacitates any werewolf it touches in one episode but in another he gets taken down in one blow.
If you didn't like the nauseating, sappy romance between Scott and Allison in the previous season, well too bad, it devours their screen time like a malignant cancer . Their relationship is once again star-crossed lovers because it would be perfect otherwise. They can't even think up a viable excuse why they broke up or aspect they find at fault with each other. It's not even that romantic, they are generally too busy trying to eat each other's face, and this climaxes (cringe) with them having sex in the deep, dark woods when they are supposed to be watching an homicidal lizard monster. This is slasher movie victim stupidity.
Also remember the female werewolf that fans were hyped for,well be disappointed as she has little to no point in the story. She suddenly pops into existence with no foreshadowing and we are expected to care as all the characters throw their sympathy to her. Then she gets bitten, and makes a full personality 180 to a sexual predator, humping Scott's leg like she's in heat. It amazes me that television can write complex and mature love triangles with two men but when 2 women are involved its ultimately simplified to the good girl and the slut. What little we see left of her is spent with her screwing up Derek's simplest instructions in a truly Team Rocketesque fashion.
Teen Wolf has lost its bite.
