I hate to be a killjoy, but to me, this Bentall 6 Tower is "bitty" looking, in that it is on the wrong scale for the central city area.

Also, although I like the original use of angles (such as on the Georgia) this one looks awkward and top-heavy. It just isn't aesthetic. It has no elegance to it. It has style, yes, but poor style (IMHO)

Call me an intellectual snob if you will, but my gut reaction to it is 'ho-hum' at best and 'yuck' at worst. Sorry if I'm going against the flow. I would have expected something classier from the Bentall group.
