I have not been yet to Universal Singapore but will pay the place a visit when I am next in that part of the world.
It looks like a scaled down version of the one in LA which is no bad thing having been to that one twice and loved it.
I have also been to Warner Brothers Movie World on the Gold Coast Australia which until now was the closest thing Australians could get to a Hollywood type experience without flying to the USA but doesn't compare.
So based on all these judgements I suggest do a visit to Universal Singapore You will love it.
