I like the animations in the lockscreens. The smoothness is ok but not great. And of course I dont want the chinese in the themes. I dont know how long this has been out but if its pretty new, its a good start. It could be just as good if not better than widgetlocker with more development. But until then, its not on the same level yet as widgetlocker in my opinion. I'll keep it on my device and watch for updates though.

Everything before that doesn't matter.
