And, in a funny way, things that suck can be very inspiring. Good stuff is the most inspiring of all, of course, but terrible, irritating things can also light a fire under you in a funny way that's hard to explain.
People who like to write often have heroes that they admire. Why not have enemies, too? You don't have write about it. It can just be in your head, a little fuel in your engine.
That doesn't mean that you fill your life with things that suck, but a little bit every now and then, when it honestly piques your interest isn't a bad thing. If it helps, it helps.
And I think that's why I "hate watch" on occasion.
(Also, I can only speak for my own process. No one else's, obviously).
