Yes, Hollywood Boulevard and Sunset Boulevard are fantastic, but the rest of the park is honestly just a thematic mess. At Universal Studios, only one section of the park focuses on movie production, and that's Production Central. And, lo and behold, things are actually still filmed there! Wow! Maybe not Hollywood blockbusters, but at least the soundstage at Universal are pretty much in constant use and serve purpose.
And if you compare similar themed lands, such as Streets of America at DHS and New York at US, US blows Streets of America out of the water. New York at US does a better job in putting you actually in New York. At DHS, you turn the corner and see the metal scaffolding that holds each flat facade up, clearly trying to pretend that you're on a Hollywood backlot. At US, New York feels more intimate, with all of the little alleyways and places to explore, and not just like a vast and giant wasteland like in DHS.
