good news according to me icobench is the best site of ico review the high mark means that the experts believe in the project, and is a good additional advertising...
There is only one rating by a human person who gave Cryptoflix a perfect 5/5/5 score. The other rating is from Benchy the ICO analyzer bot, which only checks for things like the existence of a whitepaper and the amount of social media channels.
Yes, as long as there aren't some more experts' ratings the score doesn't mean anything. And even with a rating of 20 experts it's always recommended to check the project for yourself.
