It varies. EVA_Unit_4A panned the Goseiger stuff and Baltmatrix praised it to the the point I asked him for his opinion on an eBay lot I was eyeing to buy (Thanks again man! :D)
I've heard several negative opinions directed to music I liked and still kinda enjoy to the point I feel like I'm doing something wrong by listening to Nickleback's All the Right Reasons. Or anything Nu Metal/Alternative/Punk/Angry White Boy Music.

And even though TJOmega would hate me for it, I like Armada Hot Shot.
What? The pack-in mini comic that served as the base for JaAM sold the guy for me when I was 8.

i watch and read some reviews to be informed about a toy which is why I like Vangelus a lot. He alone has convinced me to buy the mighty form kuuga of some form or another at some point. He also introduced me to kamen Rider pretty much.

Maybe it's because I like to review stuff (and on this forum at least, much to people's annoyance it seems haha) I've always appreciated reviews.

I've hated that attitude of 'well I want to make my own opinion!'. That is fine, but in a world where nothing is for free it's useful to have reviews so you can make the best decision for yourself, or at least assume the best possible choice for yourself. It may turn out to be completely wrong, but it's still cheaper over all than simply trying every damn thing that even slightly takes your interest so you can make up your own mind.
