Let me clarify .. I meant "ride" attractions .. which DHS always lacked. Ride attractions are repeatable, have queue lines and usually pretty unique experiences.
The only "ride" attraction that was lost over the past few years was Backlot Tour. While the backlot area was pretty large, there wasn't really much to do there except the Tour (and eventually the Lights, Motor Action show). Streets of America was just an area that had nothing to do, Lights Motor Action was a show that only ran 2-3 times a day and Honey I shrunk the Playground was a playground (a fun one for sure and something the Disney parks could have more of in my opinion).
Currently DHS has 4 "ride" attractions. After Toy Story Land and SWGE and Mickey's Runaway Railway, DHS will have 9 "ride" attractions .. double of what it has RIGHT NOW and more (by far) than it ever did. A good thing for sure.
It will no longer be a "half day" park and will have a lot more repeatable attractions than when it was filled with mostly shows and tours about the making of movies.
