By today's standards I'd still give it a 4 star but by yesteryear I give it a solid 5. I LOVE how they actually built large props unlike today's TV shows that lean heavily on the crutch of C.G.I. which looks like they are splicing a glorified cartoon with real images and people. For example in a few episodes they used giant telephones which looked realistic but today they'd have a CGI telephone that is obviously cut and pasted into the scene. But I guess CGI is a lot, easier, cheaper and economical.
