Guilty pleasure films

The Titfield Thunderbolt. Rail vs road where - unlike pesky real life - rail actually wins.
Sorry, should have said spoiler alert.
Dane Cook movies.

Specifically, Employee of The Month and Good Luck Chuck, both well known as awful films and absolutely panned on Rotten Tomatoes
I just don't understand how these can be classed as guilty pleasures. They are some of the finest films ever made. It's like saying citizen kane.
I guess I see them as films that aren't necessarily cool to admit to liking in some people eyes! You're dead right though they are superb films! Look kids, Big Ben, Houses of Parliament.
