Eric Stonestreet as Fizbo in "Modern Family"

Wednesday is another busy night of fall TV. Does anyone else wonder why the networks are cramming all their premieres into one week? It's bit daunting and you can't watch all the shows to figure out which ones are any good.

ABC returns its highly successful Wednesday night comedy block tonight with "The Middle" (8 p.m.), "Modern Family" (9 p.m.), "Cougar Town" (9:30 p.m.) and a new series, "Better with You," filling in the 8:30 p.m. slot.

Of the four, "Modern Family" is the only one I recommend. It's possibly the best comedy on any of the networks. Of the others, "The Middle" and "Cougar Town" (with Jennifer Aniston guest starring tonight) are decent, but not worth tuning into every week and "Better with You" looks like it's headed for an early cancellation.

The other big premiere tonight is J.J. Abrams spy series "Undercovers" at 8 p.m. on NBC. It has some great action--especially the opening sequence--but tries to incorporate some comedic bits that fall flat. Abrams usually produces quality stuff, so maybe "Undercovers" will improve.

At 10 p.m. "The Defenders" starring Jerry O'Connell and Jim Belushi airs on CBS. Early reports said it's not as bad as it sounds, but I find that hard to believe--it's O'Connell and Belushi for Christ's sake.

A better bet at 10 p.m. is "Terriers" on FX. Starring the lovable Donal Logue, it's one of the best new shows of the year and tonight's episode showcases "Terriers" wonderful mix of black comedy, quirky characters and sharp writing.
