So guilty pleasure just without the guilt part.
For me it's a few movies actually, I know their not good ones but I love them and don't care what people think.
Swan princess (I heard people call this genre Diet Disney/Disney light, Don Bluth's Anastasia is supposedly the same category) I've loved it since I was kid and still do even though I can see it's flaws as an adult.
Into the woods, I must have seen this one 5 times last year! it's has... issues.... alot of issues, infact I often skip Depps part but I love it!
The nightmare before Christmas. I see alot of merch. for this one but I was a kid when it came it and it wasn't popular back then, infact I was the only one that went crazy for it and just HAD to have it on every year for Halloween. I showed it to my niece and nephew recently and they were not impressed, I think it's aged rather well though.
