Here is the opinion of someone who has visited both resorts recently and has spent time at DCA during four trips over the last 3 years:
1. DLR has a much higher percentage of local visitors than WDW. A lot of these people have Annual Passes (I believe about 600,000). Unlike most WDW AP holders, DLR AP holders visit the park regularly (every month or every week in some cases). They have a much stronger sense of ownership than do WDW visitors. Therefore their standards are much higher for DL and DCA than are WDW visitors. IMO, if any of the Epcot/AK/MGM parks at WDW were built in place of DCA, the criticism would have been similar to that of DCA.
2. DCA does have some chinks. There is a bit of evidence that the park concept was not vetted with Disney Imagineering, and was pushed through on a reduced budget by senior management who had little idea how to build a theme park (BTW, all of these people have since left the Walt Disney Company). The original budget for DCA was $2.1 billion, and was cut to $1.4 billion. Of that, almost half was spent just on the GC Hotel. So only about $700 million was spent on DCA itself. Many knowledgable people would argue that to build a successful Disney park, several billion dollars is required. DL regulars who are aware of this feel like Disney short-changed DL fans and they deeply resent it.

3. Many of DCA's critics claim that DCA is "not a true Disney park". When questioned further, many of them have only ever been to DL and never to WDW. So when they criticize DCA, many of the criticisms could be equally made of the WDW parks. Except they do not know that. Many of them have an unrealistic understanding of what the WDW parks are like.
4. Like MGM and AK at WDW, DCA is really a one day park. However, one difference at DCA is that it is located so close to DL (the gates are within 100 yards of each other) that it is very easy to go back and forth. On my last four trips to DLR, I have never spent an entire day at only one of the parks. In other words, I have parkhopped every single day. And sometimes I have hopped 3-4 times on the same day. So thinking of DCA as a one day park is a bit misleading when compared to MGM or AK.
5. Many people criticize DCA because it has "too few" rides. In fact, it has more rides and more or an equal number of headliners than the WDW parks except for MK. DL fans are spoiled because DL has so many headliner rides - several more than MK even.
6. IMO, most of the DCA criticism comes from locals. Those who visit only occasionally from out-of-state tend to find DCA to be a pretty cool place. Not a great place. But definitely worth their time.
7. DCA attendance has never reached original projections. It was planned to have 7 million a year, and in reality it has only had 5-6 million. And Disney had to make compromises to get that number there, such as changing their AP rules because in its first year no one was going to DCA.
8. In 2005 DCA was the seventh most attended theme park in North America, with 5 of the 6 parks ahead of it Disney parks. Here is a link to the top 25
