Harry Potter. I randomly saw one of the middle movies on a plane once (not sure which one). It couldn't keep my attention.

"Bringing out the dead" Nicolas cage . This move was so tedious for me I begin counting every second and every minute I walked out halfway through I just couldn't take it anymore . Bored as fuck

Top Gun. Can you squeeze any more shower scenes in a film?

The Big Lebowski. I love White Russians though. The drink, not the Trumps.

Inglourious Basterds. Too much bullshit, not enough mayhem & killin' nazis

Pretty Woman.

Did not totally hate but gave it a c- at best Forest Gump

I loved Pulp Fiction! What was it that turned you off?

Le Miz, Titanic and Cats. Not that this is the reason I don't like them, but all of them being so long made watching them even more painful. The groups of people I saw them with couldn't stop raving about how good they were so it was also torture through the rest of the evening while they relived the "best parts".

LOTR series. I went with my kids. I remember looking at my watch thinking it was 3 hours of my life I'd never get back. My kids liked it, I like spending time with my kids.

The Piano. Pulp Fiction a close second....several hours I'll never recoup!

Gravity! I didn’t watch it to the end .....sorry if anyone loved it!

I know this makes me sound infantile since it's a child's movie anyway but Frozen made me want to shoot myself in the face

Titanic

Was never crazy about Forrest Gumps movie

Anchorman. Ugh! I watched about half an hour of it with some friends, and not one of us was laughing so we decided to shut it off and do something else.

I don't know if everyone liked it, but "The Bodyguard" was the MOST boring movie I have EVER watched...well, kind of watched; I fell asleep through some of it...at the theater.

Oh geez where to start ?
I'm kind of a bee-hatch about movies, etc. Unless super compelled to be patient my personal rule is something has 20 minutes to grab me or I've got other things more interesting to do.
I'm not sitting through some formula creation just to say I watched a thing. /i'm bad i know

Titanic and Forrest Gump.
