In the before times, I rarely thought it was worth buying. As another poster said, I thought it only made sense for longer trips with large family groups, or maybe if it was a special occasion trip, like your first visit, rare visit, or big celebration. I also felt it was harder to make good use of it during busier park times. Personally, we'll wait in line for attractions, minimally for characters, but we're not generally inclined to wait in line for a photo. I also tend to like our own photos best.
One tradition we have, and it started with a Jungle Cruise joke about the high-biscus and the low-biscus (hibiscus), is to take a photo of us whenever we see a hibiscus at any place like a theme park. They are very photogenic flowers! It started as a joke, but now we love our collection of hibiscus pictures. IMO, they are much more unique then the classics WDW offers.
