Perhaps. It largely indicates though that he hasn't dug deeper into the game's mechanics to find the differences and has judged it based on what it inherently looks like...which is Smash Bros. There really isn't anything wrong with that assessment. If there is something the average person compares your product to inherently just by looking at it you have a problem and need to market it better (unless that is your goal of course in order to increase your sales).
"Just a ripoff..." does though.
Let's not kid ourselves, the similarities don't stop at the amount of characters and the camera. They could have picked other formulas than just SF or Smash also. They could have alternatively changed up the smash formula in a very visible way (like how about teams and/or tag-ins ala MvC?).
Let's put it this way, Sony wanted a product to celebrate its characters. There are plenty of games that celebrate a large cast of characters drawn from various sources, and fighting games are generally the best way to do it. But really they could have only gone a number of ways, namely a SF style game or more of a party fighter. If they had made it more like a Street Fighter game there wouldn't be droves of people out calling it a rip off. So why is it that only Smash Bros is allowed an untouchable formula? Especially when the only similarities are the way the camera works and having four characters on screen
