To be fair, I don't think the fact that DHS is currently overrun exactly negates the criticisms people had of GE. The fact is, this excitement didn't happen until RotR opened. If anything, I think the current excitement validates at least some of the criticism -- that the rest of GE is a bit lifeless or dreary, that it lacks a little "something," etc. We can see now that people can and do get excited about Star Wars stuff, if it is done really well. It sort of highlights the fact that this ride design is what they got right, and despite a lot of money and attention to detail, the rest of GE just doesn't 100% resonate. Hopefully the ride will draw people in enough that the rest of the land can be appreciated, but it's probably the case that the past few months don't "prove" that GE is a wild success or a dismal failure, but rather a (pretty fascinating, if you ask me) mix of the two.
