It’s a bit dramatic to give it one star.
It was a good movie, I enjoyed it. Was it as good as it had the potential to be or as the trailers implied? No. But that doesn’t make it a one star movie. It was flawed, not a great part of the matrix series but still a good movie in itself.
It’s just because everyone is thinking about it in relation to the rest of the matrix Series that it has got low reviews. Other MUCH worse movies have got more than a 2.7 star rating because they are standalone movies so there is nothing to compare it against.
