How much of your Blu collection consists of Blind Buys?

[DaleDark]

My blind buys:

Apocolypto ("he may be insane, but he knows plot structure")
The Departed
The Host
Letters From Iwo Jima
Ocean's 13 (gift)
The Prestige
Superbad
Vacancy

The only one I was a bit leery about was Vacancy, but my brother said (and I generally trust his judgement) that while he thought the ending was a bit weak, the movie was otherwise really good (I enjoyed it also). Other than that all of my blind buys are "educated" blind buys (word of mouth, filmmakers who's other work I've enjoyed, etc......).
