Was just about to post the same comment. Both Phil and Andrew over at AC also had less favorable impressions about the UI, saying while the rotating bezel is great, similar to the Apple, navigation or completing actions is often disjointed or required too many steps. And the setup process was often incredibly tedious, requiring interaction with both Google Play and the Galaxy App Store to get apps working. The voice functionality being less than stellar is problematic too. I use Siri more than just about any means of interaction on my Apple Watch and if she didn't work as well as she does, I might've have ditched the watch altogether.
