Under the Dome 10 p.m., CBS
It’s getting wacky and desperate inside Chester’s Mill, what with the accidental shootings, nefarious priests starting house fires, and unexplained seizures. While the acting has proven uneven so far, and some of the dialogue is downright hokey — especially among the teen characters — I’m still intrigued enough by the premise to stay tuned. And apparently, I’m not alone, since the adaptation of the Stephen King novel is a solid ratings success. Pictured: Alexander Koch and Rachelle Lefevre.
