I think the key to remember is the theme at DHS was more than just a theme. When the park first opened as Disney-MGM Studios it was an actual working production studio. The backlot was actually used for production (films, television, music videos, etc.) and the animation building housed a room of actual animators working on current Disney productions (Lilo and Stitch being fully animated there if I remember correctly).

If you never had the chance to visit before the studios themselves shutdown I could definitely see how it just seems like poor theming/planning. If you were able to experience the park in the first few years it was open you'd have at least the memory of how it once felt cohesive. Or at least that's my opinion as someone who did.
