No ‘‘Lost’’ tonight, so we can watch the doctors try to free a child from a hardening block of cement for two hours. Sounds like an episode written by Samuel Beckett. Also tonight, Derek (Patrick Dempsey) and Meredith (Ellen Pompeo) are supposed to resolve their relationship for good. Or at least until the next sweeps month.

Recent widow Halle Berry invites Benicio Del Toro (right) - a heroin addict and her late husband's best friend - to live with her family. The movie's tastefully directed by Susanne Bier, but most of the characters are simple and dull. Were there such a thing as a low-carb melodrama, this would be it - all the tears, half the guilt. Del Toro gets to act up the sort of squall you expect from Berry, who doesn't act up at all. (R; runs through May 28) - Wesley Morris
