ET & Simpsons - could move people away from the hot spots of NY & MIB, so I'd like to see them try. Unfortunately, they are older ride systems that maintenance might prevent them from operating past a certain time.
Transformers - It's an awkward location unfortunately
Horror Makeup Show - it can handle ~600 people a show and they can run shows far closer to each showtime than they do now during normal ops. I've mentioned they can use this space for a different, yet similar, show. Definitely doable.
Bourne - They shouldn't run Bourne, but they should utilize the theater for something. You can display anything on the screen and roll out an assortment of temporary stage props overnight like they do for the scare zones.

As wild as this sounds, HHN isn't necessarily fully crowded, just lopsided towards the Fallon corner of NY and World Expo.
Outside NY, San Fran and World Expo, HHN is fairly empty. Even this past year the central park zone was decent crowd-wise. They really need something to draw folks towards the Hollywood/DreamWorks side of the park.
