Advice on views for comments system of very dynamic website

I would have a view with the layout for a single comment, one for a single critique etc.

Then just load that view, passing across the data for the specific item, using a loop. You could do this via an ajax request and then append the HTML returned, if it was for a "see more".

Otherwise, just have a foreach loop for the initial comments you want loaded, and load the comment view over and over, passing the item across to the view file.
