Never did like the Enterprise-E, felt like the took the Connie-refit, the Excelsior and Voyager put them all in a bag and stomped on it. And the color scheme of the interiors are downright depressing.
They ran out of ideas. The TNG era designers' natural tendency was to believe "thinner! sleek! better!" so after D (a so-so design, IMO), here comes E, which was a horrible mashup of the Excelsior
and who knows what else, with all of the off surface stripes and angles.
They never appeared to be functional, powerful
ships, but glorified model kits.
