I was the exact same with soy sauce!!! It looked dicey and I didn't know what it was... but finally tried it with sushi, and there is NO going back.I ate sushi the other day and I did the strangest thing too. I used soy sauce and you know what? My friends were right! It's a good combo! Gave it an unusual salty taste.
I never bothered to use soy sauce before. Its weeeird. It looks like maple syrup and before this point I never knew what it tasted like.
The yellow stuff that looks like boiled cabbage is alright. Wasabe still tastes nasty. Even with soy sauce.
