I think it should go. I don't find the building all that attractive, certainly the parking lots aren't and my gut feeling is that nothing would happen for years on that site if they leave it there. It would just be an eyesore.
Of course, that's also a possibility if it gets demolished but there does seem to be a bit of support behind the idea of putting a "cap" over crosstown blvd and reconnecting Wylie and Webster Avenues to downtown. If they could build a really vibrant community there, that would be a huge asset.
