we love it. If you're a "get the most bang for your buck" kind of person, then I can see not caring for it since it's mostly retail stores and restaurants.
We love it b/c I vastly prefer TS dining to QS (I'm on vacation, don't judge me) and DS has the most TS dining variety on property. Frankly, the TS options at MK and AK aren't that good (Tiffins used to be good before they made the menu super casual), so there's only two parks (HS and EPCOT) with decent TS dining. Many of the resort hotels have good restaurants, but getting to/from the different resorts just for a dinner can be obnoxious, so unless it's a special occasion (Victoria & Alberts, Yachtsman, Jiko), I'm not overly inclined to venture outside my immediate resort vicinity for food.
Don't get me wrong, the options at DS could be better. But at least there's variety with Morimoto, Jaleo, Frontera Cocina, STK, Boathouse, Paddlefish, Terralina, Raglan Road, Homecoming, etc. The dining variety alone (with at least a couple hours at Jock Lindsay's Hangar Bar in between) makes DS a must-do for us every trip.
