UPDATE: Sorry, I was too busy at the day job to update this thread as I had planned. For those who do check back, we have Adam B. Vary's recap at EW.com:
There may not have been a Lacey Schwimmer-Mia Michaels breakout moment to set the YouTubers all a-twitter in last night's top 20 episode of So You Think You Can Dance, but in spite of all of Nigel Lythgoe's unsubtle grandstanding about how great this season is turning out to be, I've got to agree with the guy. With only one or two truly unsatisfying performances, and nothing even approaching an outright disaster, last night went a long way to assuaging my frustration with Vegas week. Which isn't to say there weren't some dancers who still had me scowling about how, exactly, they were worth passing over Evan Kasprzak and Brandon Bryant, dancers with personality and good looks and skill and technique and panache and poise and great dimples...but I digress.
