What do you mean? What would you like to be done differently? I am sure Samsung and others will add to it.
Well for one, you can only have 1 widget per lock screen page. Unless you use a full length password, it's faster to just unlock your phone and go about your business (aside from the first screen).
To scroll to the next page you need to grab the edge of the screen instead of swiping page to page.
I believe (altho it's been a while since I tinkered with it) that not all widgets are available. I don't remember if you get full control of the widget, so someone else would have to speak on this.
The layout is awkward in that each page has its borders showing (this one is tough to describe). But think how Sony has set up its app drawer, and this is how it looks.
Don't get me wrong, I wish Apple would implement lock screen widgets. But I also think the Apple lock screen is set up that it needs lock screen widgets more. Because when you wake iPhone, it wakes to the lockscreen. But when you wake a stock Android phone, it doesn't always.
