I'll use this thread as proof that game reviews can't tell you whether you'll like a game through the score alone. I take the opposite approach that the OP does. Instead of only looking at review scores, I only read the wordy part of the review. I don't even think reviews should have numbers.
That being said, he totally doesn't get Smash Bros.. The whole point of the game is to be an accessible fighter. All the fighters use the same button combinations so that a beginner can switch between characters without being at a disadvantage. The game is not a hardcore fighter (particularly Brawl) it's primarily a party fighter.
Read the reviews, don't just look at review scores.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
