There's a very good reason why you never got the vibe of Steampunk,
@shiekra38 . It's because the aesthetic of '94's Tomorrowland was "Raygun Gothic". (Catchall term for a visual style that combines Googie (Hello, Space Mountain!), Streamline Moderne and Art Deco for use in retro futuristic sci-fi environs. A great example is Buck Rodgers and Flash Gordon which were certainly inspirations for the land.)
Plain and simple, TL's style was not Steampunk, and I have no idea why people are saying that.
As for the new sign, I'll admit the minimalistic/modern look doesn't really do it for me as that look can easily come off as sterile and bland. Though I'm curious to see if they'll actually convert the entire land in that look unlike the past attempt which stopped halfway through.
