Julia,

You are the God of your story. You can do anything you want! You pointed out to books that have them - the Epic Fantasy, Name of the Wind is positively chock full of them! That doesn't make your book bad.

But. Readers today are used to sharp, fast reads. They want an immersive experience. They want to BE your character! Filter words keep them at a distance - keep them from being in the character's skin.

Here's an example:

She saw the mess in the living room, and saw how angry he was about it.

See how you've showed us what's going on, like in a movie?

Compared to this:

The couch cushions were torn, the dirt from the potted plant, scattered across the carpet. Sean stood, staring, his face painted with anger.

Okay, that wasn't great, but see how the second puts you in the room? She is the POV character, so if you mention it, we KNOW it's because she saw it.

Neither is wrong, but the second brings the reader closer. See what I mean?
