Should I watch Alien?

I've always had a sorta crush on Sigourney Weaver, admire the hell out of her

I honestly don't know anything about the Alien movies except for references to an Alien popping out of a chest and those pictures of her in her underwear that people post, I think that's Alien? And it's on a lot of must watch movie lists

And I do love Sci Fi

But I'm not a fan of horror movies, or gross movies

I'd say my threshold is Zombieland, I love it, have seen it tons, but still need to look away at certain parts

Final destination and Paranormal still gives me the heebie jeebies and nightmares occasionally even after all this time

I will abide by your decision

Edit: Seems the overwhelming consensus is that my wife and I need to watch this asap, thanks for all the responses!

Edit 2: ok I've seen more than a few comments about how this is fake, or I'm an idiot. So I'll post my response here cuz I'm getting tired of putting it in the replies.

I grew up a Jehovah's Witness, wasn't allowed to watch a lot of movies, Definately nothing worse than PG13 and sometimes not even then. Grew up on Star Trek, Star Wars, Stargate, Back to the Future, MST3K, etc.

Since I left the church I've been working on an insanely long list of movies I need to catch up, mostly r-rated.

Alien has always been put on the back burner because i had the assumption from the very little I saw that it was horror/slasher, and I had bad experiences with watching horror i.e. final destination, paranormal

So I figured I'd ask and a couple nice imgur-ians could let me know without spoiling the movie, which would probably happen if I googled it

Love movies like Edge of Tomorrow, Gravity, Arrival, Matrix, Terminator, LotR, total Marvel Junkie, as well as drama, suspense, yada yada

Other movies I haven't watched yet - any of the Godfathers, Stanley Kubrick, Quentin Tarantino, Predator series, my list is huge

The end
