I think an argument can be made that, regardless of whether any individual likes them, the overall aesthetics of the Bayverse TFs are, objectively, bad. The designs are overly busy and simultaneously somehow undifferentiated. There is no school of design that endorses that sort of thing. Even if you argue that they are somehow intended to be Impressionistic in nature, it is Impressionism appropriated for an entirely incongruent artform (motion pictures, that is); or, at least, incongruent in the manner that Bay attempts to use it. TL; DR: They fugly. Fugly does not automatically equal bad per textbook definition, but per the current Western cultural climate, it does. Case closed.
