Sometimes less is more and there's addition by subtraction. At least, in the case of some of our favorite shows, that is definitely true. We've identified TV's weakest links this season and have determined that their removal would guarantee an immediate uptick in the entertainment level of their respective shows. Here are the major characters that most need to go, for everyone's sake:

We could make a joke about how last night's Community episode was doing an impression of a previously hilarious show by the same name, but, much like the episode itself, that seems a bit too tortured.

Bad news for people who hate musical theater.

Snuck onto the NBC schedule just as the 2011-2012 TV season enters its final months, the new romantic comedy Bent, which premiered last night with back-to-back episodes, is at once both utterly generic and kind of pleasant. The premise is Rom-Com 101: a cocky, handsome n'er-do-well contractor, Pete (David Walton), is hired to renovate the home of an uptight, beautiful divorcee, Alex (Amanda Peet). What happens next -- the erotically-charged bickering, the lingering glances, the gradual thawing of icy tensions -- is so familiar, even Alex and Pete seem to realize that they're being set up for their professional relationship to take a turn for the personal. At least the predictability of watching this routine scenario play out is somewhat offset by the general likability of the supporting cast -- which includes such experienced comic ringers as Jeffrey Tambor and JB Smoove -- and, to a lesser extent, the stars themselves. Individually, Peet and Walton are only okay, but together they make an appealing comic (if not necessarily romantic) duo. Given the strength of the casting -- and the fact that Season 1 only consists of six episodes -- we'll likely stick with Bent for the duration. Still, we'd like the show more if it would make one or more of the following five improvements:

Looks like Doctor Who is getting a new hottie companion.

After what I presume to be quite a bit of market research, IFC does not like the word "hipster" and refrains from using it at all costs. Of course, you wouldn't be able to tell from their "Upfront-Landia" -- defined by hyper-aware IFC as "network upfront combined with the only show you've ever heard from us" -- event when you first entered the party, as the vibe of the slightly industrial room at Off Broadway's New World Stages screamed "too cool" to me. (Though, oddly, the party was seriously lacking in vegetarian hors d'oeuvres, but I digress.)

After a prolonged wait, Mad Men returns to the airwaves Sunday night and few people are happier about that than John Slattery and Jared Harris. The actors play Roger Sterling and Lane Pryce, respectively, two of the four named partners in the ad agency Sterling Cooper Draper Pryce. We've seen the season premiere and while we wouldn't dream of giving anything away (because Matthew Weiner might hunt us down Hunger Games-style if we did), we can confirm that Roger, Lane and the rest of the characters you know and love are back in fine form. Slattery and Harris recently spoke with reporters by phone to discuss what viewers can expect from Season 5.

When we were first introduced to Quarles, did you ever imagine that an episode would end with him stripping down completely naked and then entering a bathroom where there's a young man tied up? Honestly, my answer is somewhere in the ballpark of: "Meh, makes sense."

Move over Al Lewis, there's a new Grandpa Munster in town.

We love the '80s.
