Guilty pleasures are fundamentally BAD movies that have little or no culturally redeeming values. But at the same time you just can’t resist watching them. Gentleman Prefer Blondes is a movie directed by Howard Hawks,written by Anita Loos and if only for those reasons alone,it does not qualify. It’s a GREAT movie.
Think empty calories.
RIsky Business is a bad movie?
I haven’t seen the movie in decades but I remember the movie being very good.
This is a college admission web site.
I haven’t seen any other movie clearly define what is Princeton Material as well as Risky Business. 
What a Girl Wants - which was just on tv a couple hours ago (and H and I watched it - for at least the 30th time?), You’ve Got Mail, Sleepless in Seattle, Elf, Christmas with the Kranks. My guilt - sheepishness? - is that I’ve watched these many, many times through the years, and still will stop to watch when they are on tv. They are perfect for when I’m doing something else and they are on in the background. (Well, we also have all the dvds so sometimes choose to watch them if it’s been a while.)
The Adventures of Buckaroo Banzai Across the Eighth Dimension.
I’m one of the 200 or so people who actually saw it in the theaters. I go whenever the local oldies theater has a screening. And we watch it at least once a year.
Laugh while you can, monkey boy! No matter where you go, there you are…
(For the vast majority who have never seen it, it has a pretty stellar cast)
You’ve Got Mail & Sleepless in Seattle – they’re on all the time!
As are the Jason Borne movies. I watch those too.
Bridget Jones
Pretty Woman
Pride & Prejudice (any version, but I LOVE the Keira Knightley one)
Freaky Friday (Jamie Lee Curtis rocks)
Oh yes. Buckaroo Banzai----I had a friend in that and I went to the premier. Truly cringe worthy but I would watch it again in a heartbeat. Maybe a double feature with Earth Girls are Easy?
Austin Powers movies (any/all of them). The sight gags make me laugh out loud.
Airplane. It’s so funny but so politically incorrect.
Personally, I do not like watching a movie over and over. But did as a kid. Wizard of Oz and Peter Pan.
H watches Saving Private Ryan over and over.
Omg Buckaroo Bonzai. I had the biggest crush on Jeff Goldblum after seeing that movie. Thirty years later I still kind of do. That’s a perfect guilty pleasure movie. I’ll have to rewatch it.
Guilty pleasure for me means a movie you know is objectively bad when measured by artistic merit but you love it nonetheless.
Well maybe then Cabin in the Woods. Haha
Many of my guilty pleasure movies have been mentioned. I will add:
Yes!
And, while it’s not porn (lookin at you, @dstark :P), it totally meets the definition of guilty pleasure.
The Devil Wears Prada.
The first Star Trek movie. Just a rehash of a plot from one of the episodes, but when they bring the lights up on the Enterprise for the first time, well, it just restores one’s faith in humanity.
But I am NOT admitting to watching the Magic Mike movies!
The Lost Boys
Guilty pleasures also include “age-inappropriate” movies… Like watching animated stuff when there is not a kid in the house. 
I’m assuming you mean Disney-type animated and not something like Miyazaki films
The American President is another one that sucks us in every time. Just about spit out my drink the other night when Trevor Noah showed Michael Douglas defending Annette Benning - and then showed Ted Cruz using almost the exact same wording to defend Heidi! He must be a fan as well!
“West Side Story” … Don’t know why, but I just cannot change the channel if I land on that. Then, of course, I’m left singing the songs for days.
To me the guilty pleasure part was that I’ve seen them so many times I feel guilty sitting there watching them again. Know them by heart. All are actually very good movies.
