With all due respect, the game's setpieces don't really start to come until about 3-4 hours in. The better ones are actually in the second hub, which clearly shows that id was more comfortable with the tools as the game was maturing.
I posted some of the items I found impressive in the patch thread. While I agree that some of the "invisible walls" are frustrating, after you get beyond that there's some amazing work in there.
I'm in no way disagreeing that the game had birthing issues, but I can see that once they iron out there's going to be some cool stuff that can be done with it.
