Compare it not to the best episodes of Buffy, Angel and Firefly. Compare it to the first few episodes of Buffy or Angel. Are they about on par? I think they are.
It took me until episode seven before I really got hooked on Buffy. It took an entire season of Angel before I felt that got going at all smoothly. Firefly is the exception but Firefly was an exceptional programme to begin with (and who's to say that wouldn't have turned South had it continued longer?).
Of course you're not going to see "Passion" in the first three episodes. You have good reason to give it more time.
