It's a good series.  I'd like to know though in episode 1 if both pills were poison pills or not.  Most concensus says it was.  But i'm surprised Sherlock didn't figure that out?  It would have been nice closure, HAD he said in the end "I knew both pills were poisoned".  

It's also puzzling why Watson ran off protecting the girl in episode 2 at the museum when he should have remained and protected her.
