The 3D medium had some fantastic art. There were a lot of gimmicks in movies you'd expect, like harold and kumar go to whitecastle (not meant to be a serious movie). But there were also fantastic shots and art direction such as in tron: legacy and prometheus, where 3D provided a much deeper feel of space and made certain shots that much more emotionally resonant and beautiful.

There were a lot more misses than wins, as most directors saw it as a gimmick, but not everyone did. The folks who thought carefully about how extra dimensions would affect a shot (even when it was done in post rather than shot on 3D cameras) made some wonderful art, and it's a shame so many folks missed out on it because they weren't able to see past it as a gimmick either.

Home 3D movies were never good, you didn't miss much.

They disappeared for a reason. It was a crappy gimmick.
