3D movies, I remember everyone being so excited for shit like Avatar because it was a 3D movie without the dumb red and blue lenses. Then it turned out to just give you vertigo.
Or even 4K TV. Like it looks marginally better if your face is jammed into the screen, but all it really does is suck up way more bandwidth and cost $400 more.
I wish they canned all the space/civilization stuff. If they could have just gone deeper on the first two stages it would have been so much better.
