Despite their massive and persistent popularity, many TV-watchers still dismiss reality talent shows as boring, formulaic and silly. But it's impossible to deny that the likes of 'American Idol,' 'So You Think You Can Dance,' and 'The Sing-Off' exposed us to an incredible array of unique (and at times bizarre) talent in 2010. Many of our favorite reality talent show contestants this year weren't the ones who ended up winning; it was often the zaniest, most original acts that left the biggest impressions. We've narrowed our favorite runner-ups and also-rans down to the five most memorable. Which one of these almost-winners impressed you the most?

The Nominees:

Crystal Bowersox: She may not have won 'American Idol' this year, but the raw talent on display from this runner-up was simply astonishing every time she sang. With a throwback singing voice reminiscent of Janis Joplin, Bowersox stood out almost immediately. Combining that old-school talent with a humble and sweet personality, it's no wonder she's sold more records so far than any other contestant that season.

Prince Poppycock: Poppycock defied the odds with campy and theatrical performances throughout his time on 'America's Got Talent.' Yes, he initially seemed bizarre, but he proved to be compelling in everything he did. Many tried to dismiss him for the sheer ridiculousness of his productions, but there was no denying the power and control of his voice. Sharon Osbourne declared him the "male Lady Gaga," but we think Poppycock is in a class all his own.

Fighting Gravity: These college students risked it all for their chance at fame on 'America's Got Talent,' delivering captivating, complex dance routines time after time. Each Fighting Gravity performance was filled with illusions and cool dance moves that demanded multiple viewings just to figure out how they were doing it. That they came out of nowhere with a fully developed, unique Vegas-style show from their first audition was simply remarkable.

The Sing-Off: The talent was so impressive across the board in this acapella talent competition that we couldn't even narrow it down, and instead have to give our nod to the entire five-episode season. Riding the coattails of the 'Glee' phenomenon, 'The Sing-Off' exposed us to an incredible breadth of talented singers. Committed may have taken the title, but the audience was the true winner for getting to experience all of the finalists.

Alex Wong: His time on 'So You Think You Can Dance' may have been cut short, but that doesn't take away from the transcendent beauty of his work while he was there. Wong's contemporary performance with 'SYTYCD' All-Star Allison Hoker was pegged by judge Mia Michaels as "the best, hands down, piece of work danced on the 'So You Think You Can Dance' stage anywhere in the world up to date." Taken down by injury, Wong has been invited to return next season to continue his magical journey.
