I think they need to work on making the quality consistent, but I know from reading on the boards over the last few years that while many of us, myself included, really like the new, interesting things they are working on, there are still many out there that don't like the new "avant garde" combinations at the restaurants or the veering from the traditional. Even though Hungry Bear offers yummy onion rings, sweet potato fries, and a zesty vegetable slaw, surely you remember reading the uproar about getting rid of the regular fries. And I have seen lots of posts over the last couple of years from people saying that their kids (older than toddler meal age) only eat chicken nuggets or plain mac and cheese, so there is surely a market for keeping some of that boring, bland food as not everyone has an adventurous palate, especially kids.
I think they need to work on improving their basics...the burgers, the pizza, etc. at the places that will retain those simple items, but I'm one of the people that really enjoys all of their new food offerings.
