Republican National Convention - Primetime convention coverage on broadcast networks begins at 10 p.m. tonight. If you want wall-to-wall coverage, your best bet is to head online or to cable. Tonight's highlights include speeches from Ann Romney, Govs. Chris Christie (N.J.), Bobby Jindal (La.) and Bob McDonnell (Va.), former senator Rick Santorum. Here's much more information about RNC viewing.

Pretty Little Liars (8pm, ABC Family) - In the summer season finale, Maya's murder trial gets underway, and Emily can't withstand the media attention surrounding it. "A" then extends an olive branch to the girls, who are skeptical about the sincerity of this offer.

MasterChef (9pm, Fox) - Four hopefuls remain, and they're forced to work in teams of two to prepare a gourmet meal for three world-renowned chefs: Daniel Boulud, Alain Ducasse and Guy Savoy. The losing team must face off in a tense souffle test to earn a spot in the Top 3.

Mysteries at the Museum (9pm, Travel) - New England museums are spotlighted. Included, a look at a dress that is linked to a purported alien encounter.

Covert Affairs (10pm, USA) - Annie goes to Cuba with Simon in order to gain more information about his affairs, but she doesn't have any backup from the CIA during the trip.

Collection Intervention (10pm, Syfy) - A couple shares a one-bedroom apartment with a dog and ... thirty thousand comic books.

If you watched last night's premiere of "Collection Intervention," you might experience deja vu if you tune into "Toy Hunter" (10 tonight, Travel Channel). Apparently, a lot of people collect Star Wars figurines.

Yet while they overlap in depicting toys and collectors, the shows have different spirits. "Toy Hunter" features Jordan Hembrough following leads, moving from basements to storage rooms to attics, in search of toys he can buy and resell. He doesn't care if you have clutter, only if you've got something cool.
 

As someone who might take a bullet for my "Class of 3000" lunchbox, I get the allure of collectibles.

Yet while watching "Collection Intervention" (10 tonight, Syfy) I couldn't help shaking my head and thinking, "These people are sad."

That's because these collectors have moved into hoarder/addict range; many tears are shed over Star Wars figurines. Thank goodness for Elyse Luray, a former vice president, auctioneer and head of the popular arts at Christie's who comes in and helps the crazed cull their collections and reclaim their homes.
