Nah, it's only old media that nobody remembers that's uncool if you watch it. If it's so spectacularly good or bad that everyone knows it, it's totally cool to watch. And like you just said, a shitload of them are like, the base foundation for modern meme-ology.

[Because that is definitely a word and not a thing he just decided to say right now because it was relevant to the subject.]

Also, most remakes are a kind of shitty effort at trying to recapture the magic of the original movie, so you at least owe it to yourself to watch both the original and the remake and decide which you like better. Unless the original is clearly superior like Robocop or something.
