This is a good way to get inexpensive nighttime entertainment in DL every night. DLR refuses to run Fantasmic nightly like WDW and TDR do, and with the light parade now in DCA, that leaves DL with no nighttime entertainment many nights throughout the year. This fixes that at almost no expense.
The show at HKDL is a lot of fun, and it does not employ pyro. I expect the weekend version with pyro will be even more fun.
Honestly I think the Mickey projection show in HKDL sucked and I saw it in person just a few months ago. That said I think I liked every DL projection show they done and looking forward to this one. It sounds like a good trade off, fireworks on the weekends for the bigger crowds and projections for the smaller ones on the weekdays and when the park closes earlier. But now you have a night show every night.
