Except for that Paul Kersey guy, looking at his past reviews, he's like ten flavors of crazy. Other than that, I'm not seeing anything that screams out troll or hater. I see these reviewers as someone with a Prime membership. Your videos probably shows up on their recommendations and they decided to give it a go. I get the sinking feeling that these people never heard of iClone either.
When you distribute your work through a platform like Amazon; you're leaving the safe zone of Reallusion forums. Those watching out there do not know what kind of work you put into. They only see the product as is. Not many people know how much work goes into a hollywood film, there's hundreds of people putting blood, sweat, and tears into it, but the filmgoers only see a two hour product.
This is where it's going to hurt, but this review nails it.
substance over medium.
Film is a visual medium. A bad shot is the same as a bad line of dialogue. I feel that your work is often lacking in the visual part. I've pointed this out before in one of your old films as well. Study up on composition and lighting... it's one of the biggest issues I have with your work.
It's tough... and not everyone will love your work, but it is what it is.
