This is a bit off-topic . . . . but a common plight . . . .
You must immediately recognize two things about these comments:
First, anyone who says "it needs movement" or it "just sits there, it looks dead" is speaking from an amateur viewpoint. Like you say they are just reacting to your request for a review based on presentation because they have no knowledge of the topic, and really aren't aware of all the things we are that make a web page work.
Second, you have to ask - are these people interested in your topic? Find someone who is looking for the resources offered by your site. They will have a different view; how easy it is to find guitar tabs, etc. This is your real market anyway.
