I'm not against the studio theme, but I would like to see some aesthetic changes to the park itself. The attraction lineup is decent, but with the addition of Minion Land, the front half of the park is just a big mess of Minions, UNIVRS branding and Universal Rewards kiosk... not the best first impression.
An aesthetic overhaul of the entrance (like USH saw a few years back or DCA's Buena Vista Street) will do a lot for me (honestly just some large trees is more than enough for me). My hope is that the E.T. entrance refresh will extend over to the sliver of what was originally World Expo in front of Animal Actors to get rid of some of the dated areas of the park.
My biggest gripe w/ Minion Land is the lack of foliage for shade, that asphalt is brutal.
