Either An Idiot Or A Genius

To provide fair balance to my shameless brag post from a few days ago, here is an attempted hero call that does not turn out well:

From his betting, it seemed he either had a monster or nothing. A mere pair of 10s will slow down at some point. Also the large bet sizes on the flop and turn suggest monster or nothing. Since various busted draws were possible and he hadn't raised preflop (therefore overpairs and set of 10s unlikely), I elected to call all the way down. KT, in hindsight, makes a certain degree of sense. The only thing I find a little surprising is the size of the turn bet. A set of 2s or 7s would have made sense too.

I come off looking pretty stupid in this hand, but I'm not really sure how bad it is.
