Liking an album and every song on it

I've seen lots of discussions on Reddit about albums and how some people find "filler" tracks or "skips." Personally for me I find albums as my favorite way to listen to music. I don't skip songs. I like every song on the album pretty much. Maybe I'll like one song less than the others, but I'll still listen to it each time until I start to like it. Why do so many people seem to hate half of an album?
