It's a big week for TV. Not only are a lot of shows coming back from their brief midwinter hiatuses — "Sleepy Hollow!" tonight with a two-hour episode! — the midseason replacements have begun. Here are a few things you won't want to miss this week:
Set in Louisiana, "True Detective" strives for the dusty glare of a small-town noir, in which men battle demons, real and imagined, while women stroke their brows or fall prey to their knives (there are a lot of knives). Not a new story, by any means, but Harrelson and McConaughey, playing men in two different time frames, may be enough to keep things interesting. HBO, Sunday, 9 p.m.
Self-awareness is nudging its way into frame, stuttering, stumbling self-awareness still very crowded by self-centeredness but a relief nonetheless. Hannah still gets naked plenty, though, so continuity is preserved. HBO, Sunday, 10 p.m.
