When it opened that was the biggest complaint levied against it.
I agree the marketing is out of control. However, building an attraction should still meet the need no matter how it is marketed. But for all the complains about capacity being removed, they added Little Mermaid to Fantasyland and kept Carousel of Progress and Peoplemover open, but mostly just get "meh" reactions from people. Deciding they need more mid-tier attractions, and building mid-tier attractions that can actually entice a crowd and drive revenue are two different things. It's a rare occasion indeed when a mid-tier attraction can actually pull its weight.
But yeah... as others have said part of the problem is the huge costs of WDI Attractions.
Just speaking my opinion, but I feel that the original DCA was executed poorly as a whole. It's not that these experiences were/are bad, but that the park relied too much on them. I'd say, FL has had the exact opposite problem in more recent time, to an extent.
You look at Disneyland with its B/C/D tickets, while they are modestly themed, they are nothing like NRJ, LM, SDMT, Rat.... well, aside from Rogger Rabit, which was kind of the anchor of Toontown.
To expand on that if you're interested, people love the ride, but the complaints about Toontown have always been very similar to the complaints you see about FL's newer non-E's. The land is impressive yet, has always underwhelmed. MMRR can arguably change that, but the point is that through today, it was a lasting criticism of Toontown. So, it's (properly executing B/C/D tickets) not really a new discussion, maybe in FL, somewhat.
A bit of balance is important. I forget how much Toontown was to build, but for the money spent, TSL, Pandora, and the new Rat area are underwhelming.
They're not bad experiences, but the bigger picture is what's wrong. The average guest, especially years down the road will not realize this, but in the fan community, it's easy to see why, knowing how much was spent, people are critical.
Taking it back to the original DCA, it looked cheap because it was. The newer C/D's have the exact opposite problem, IMHO, and are still relied on a bit too much, probably due to the cost for what is a pretty "meh" attraction experience.
I don't think anyone rides these newer attractions feeling like Disney was cheap, but I do feel like people leave a bit underwhelmed, if that makes sense. A similar experience to the live action theatrical remakes, really.
