Yeah, I was disappointed in it at first but after becoming vegetarian it's really nice to have it even if it's not perfect. When you have it with all the condiments it's good enough.
Have you tried the Impossible Whopper? I was pretty impressed by it. I still get it once in a while since it's pretty good and something different.
I haven't tried the whopper yet, but that's mostly because I only really eat Burger King in airports. Looking forward to trying it though.
