Grade: B+

With creepy Anonymous texts, murder, and suspicious alliances, “Pretty Little Liars” kicked off a new season with its usual hijinks. After three seasons, we’re still in the dark about who has been tormenting Aria, Hanna, Emily and Spencer. But who can blame the writers for wanting to string along what is the backbone of the show? Despite the mediocre acting by most of the cast — save Troian Bellisario — the complex weaving of mysterious storylines continues to thrill.

The premiere set up a season with even more unanswered questions. One thing is for certain: if these questions linger for too long, the show will lose its luster as well as its fan base. Executive Producer Marlene King promised in an interview this season is “the season of answers.” Let’s hope that the show lives up to that promise.
