Great Old Hollywood theme? The only parts of the park that showcase Old Hollywood are Hollywood Boulevard and Sunset Boulevard. And Hollywood Boulevard suffers from the presence of a cheesy, oversized hat. DHS once had two interesting icons (much like DCA does now: DCA has Carthay Circle Theatre and Grizzly Peak, while DHS has the Chinese Theatre and Earful Tower), but they've both been pushed aside for the plastic hat.
The hat, the 20-year-old stage shows (that are both inferior to Aladdin at DCA), the backlot tour, the Great Movie Ride (dated show scenes and a CM script that's beyond cheesy), American Idol still being in the park, and of course the barely-themed 'backlot' vibe beyond Hollywood and Sunset Boulevard.
The park needs serious help. I still love (parts of) it, but DHS would be lucky to be as impressive as DCA is now.
