Disclaimer: I have lots of very nice images shot with 50mm lenses. I also hate the 50mm focal length.
When you read an article about which lens every photographer should own, the answer is a 50mm. When I refer to 50mm in this post, I mean in 35mm terms, i.e. 30-35mm on APS-C, 25mm on Fourthirds and 18mm on 1". I have tried a lot of 50mm from Nikon, Samsung, Sigma, Canon and Olympus. I don't get a connection to them, eventhough I tend to get some great results out of them. The 50mm was always kind of the most unliked lens in my arsenal but also the one I wanted to master, because everybody has to have a 50mm after all... doesn't he?
