The play area seems to be comparable to what's currently at Winnie the Pooh. The only difference is that Disney has the ability to design this one from scratch. I fail to see why this is a problem for some people. Fantasyland rides are predominantly for children - something to keep children entertained while they wait in line is a huge step in the right direction. This type of thing takes up more space, but they can afford to do this in Disney World whereby they can't do this in Disneyland.
It's also ok to recognize the benefits of this without claiming, "Double Dumbos is better than Radiator Springs Racers woot!!11" It's a matter of perspective. Not every addition to the parks has to be an E-ticket. What it means though, is that the Magic Kingdom will be going on 22 years between e-tickets when the non-E-ticket Mine Train opens up. The additions of Little Mermaid and the Mine Train are positive ones, and it's more than ok to acknowledge that. But it's also acceptable to say that while the Magic Kingdom needed to add capacity (which is what's being accomplished here), it's also somewhat stale. A better Space Mountain refurb and/or a revolutionary E-Ticket addition would have solved that staleness problem more so than the Fantasyland expansion did.
