ELI5: Why is Windows Vista so hated?

I have absolutely no clue why Vista has become so hated over the years, and from personal experience with it, I really didn't find it bad at all. In fact, I actually liked it. So why all the hate?

Edit: I already marked this as explained, but I feel the need to thank you for all your informative answers and opinions. Much appreciated clarification from everyone who answered.

Vista's system requirements were much higher than XP's, and it dropped compatibility for a lot of software including drivers. For some people this meant that Vista ran slowly and either didn't support their hardware/software or crashed trying.

There were a lot of other changes made from XP to Vista, both in the interface and under the hood; and people don't usually like change.

Vista to 7 on the other hand had relatively little change, hardware and drivers had also gotten better, and old software was generally replaced.
