I also am not that excited by Liu in the three episodes of Elementary I watched, she's not bad by any means, and its one of her better performances (I really have a like or hate on her various jobs I have scene).
But it was certainly hurt by the fact that for the last two years I have watched, and rewatched, and rewatched Sherlock. And its no where near the quality level. While a basically 6 episode season (each is basically two norma American episodes), but its still there.
I certainly think I would have liked it better if Sherlock hadn't aired or if my exposure to Sherlock was just the recent two films (Yuck).
I watched Jeckly a year or two ago, but I don't remember anything about it, I will have to check it out again.
The other show I really really need to catch up on is Justified. I only watched two episodes, liked both a lot, but never watched again.... Oh well hiatus is a great time for that.
