I know my own taste well enough to be able to tell whether a game is something I'll enjoy or not like.
I've been gaming for well over 20 years and this is ridiculous to me. I'm always getting surprised by things. Whole genres I hated and suddenly one game can change that. Recently this happened with both Dishonored and Saint's Row 4. Both because I read several reviews and was very intrigued.
Granted, the basic score isn't very important but the actual reviews are what gave me info on the games to think maybe they were different. Without having to watch extensive gameplay and perhaps ruing something of the discovery.
Most people just keep saying "Reviews suck and the people who review them suck" Maybe you're just reading the wrong ones? The best reviews cover problems with performance and an overview of gameplay. They shouldn't just be hate or love. What's so bad about reading more about something??
Just so much blind hate on them is silly and baseless.
