Maybe because im not a huge fan of the majority of franchises used here (except probably Ghostbusters) but...
it doesnt seem particularly impressive?
The exterior parts look super blocky (RCT3 would be proud) and empty, even on the CGI renditions, and while understanding the idea behind the dreamworks zone, being all inside a building (Dubai gets super hot most of the year), I dont know if cramping those 3 franchises into a building works that good, as weve seen this frqanchises in other theme parks on outside zones, and are much spectacular. I have to say, if the lighting of the "sky" works like in the CGI, it could be cool though.
And of course its in Dubai, the paradise mostly build for rich people. I dont know how affordable for normal families is going to this theme park.
