I get nit picky too and even if a suggested tag is very close to what I want, I won't choose it if it doesn't make sense

"I am movie watcher"

Instead I add/change my own.  I made it a habit to open the I Am tags on my profile whenever I am writing a new review so that I can use the same ones over and over.  Maybe there are some I can merge so it's not all over the place but I'll deal with that later :)
