Out of curiosity, where did that review come from?The review I read said you couldn't....
Everyone's preferences are different, but I have actually enabled more notifications with my Apple Watch. Before my Apple Watch, when I had to retrieve my iPhone for every notification, most of my non-messaging notifications were on Silent so they just quietly accumulated in my Notification screen until the next time I check my iPhone. Now, with my Apple Watch I send more notifications to it because it takes one second to glance at and if it's not important then you just lower your wrist and are done.
