In the WDW fanbase thanks to folks like Al Lutz and Jim Hill, people have a false belief that DLR is a be-all end-all for Disney theme parks.
There is an awful lot they do horribly wrong, and no DL AP-touting southern Californian will ever tell you otherwise.
I just got back from DLR, and there are many - MANY - rusted handrails in the parks. There is paint missing from several areas. They don't list restaurant hours that vary from the park hours anywhere, not even on signs outfront of the restuarants, and 75% of them close 4-5 hours before the park. They lack ADA accesible ride queues for no apparent reason other then they don't want to re-drill the ground for stantion holes. Burnt out light bulbs abound. The list goes on.
As for the amazing upgrades... the floating head and new bride are the only noticeable changes in Haunted Mansion. And if you really want them to, i'm sure a few letters to management at WDW might convince them to paint the bicycles and other small items in the graveyard scene day-glo neon orange, green, and pink. Yes, there is hot pink DL's HM.
Heck, going back to the general operation there's only a small sign next to the train station to inform you that all of Fantasyland will close for the fireworks show. Not stating the time of closure or anything though. Many things about DLR are very much akimbo contrary to what the internet has been telling WDW patrons for years.
