As much as I like the beetham towers, there is one thing I can't stand about both of them, the backs!! Both towers look very impressive from the mersey, but from the back (where most people see them from) they are less than impressive. They just look like lumps of concrete.
Too much focus has been given to the fronts so that the waterfront looks nice and the back has just been neglected. This is in contrast to buildings like Unity and the planned King Edward tower that are impressive from all angles.
