Great actors, good premise, but nearly ruined by poor plotting. Here we are, at the end of two seasons, and still nobody talks. Poor communication, misunderstandings, and non-communication (silence, secrets) has driven all these plots, at least 50% of the time. Lazy writing. Stiles didn't answer Scott's call, even after 18 rings. Last episode it was the opposite, with Scott ignoring Stiles. Meanwhile, Scott doesn't tell Allison that her mom tried to kill him, so Derek rescued him, biting her. Grampa gives Allison a supposed letter from her dead mom -- all lies no doubt -- and warns her to burn it and tell no one what it says. Hence, Allison and her father never speak of it, and soon reach an impasse. Allison suddenly breaches character completely, going after young innocent wolves. I hate it when characters break away from their nature as portrayed in many previous scenes. Then, suddenly Allison and Scott are holding hands and kissing, even though he saw her stab Isaac. Then she says we need to break up. Really absurd.
Also, Scott comes up with a brilliant plan to kill Gramps once he takes the bite, but the self-centered jerk tells no one. When Derek demands, "Scott, why didn't you tell me your plan?" Scott says, "You're not my Really? So mature, Scotty boy.
And then there is Stiles, telling nobody about the young wolves penned up in Grampa's basement? And to date, he's never told his poor father anything about werewolves and other beasties. Nothing. Not even after the jailhouse massacre. I like Stiles, but the tongue thing, all hanging out? Contrived, affected, not sexy.
And don't get me started on Lydia, speaking to nobody about all the craps she's experienced.
