Once I gather my notebook and start to write, it usually starts to flow. Otherwise, I take a small break and go feed the dog or other small chore and try it again. If it continues to get stuck and drive me crazy with the details I will either look at it with a different perspective or shelf it for a few hours to a couple of days. My husband is a wonderful help since we try the items out together and he adds his opinions to a lot of my reviews. Sometimes the ideas you have for the review and the plan you have outlined for it either in your head or on notes are just not going to work. Start fresh and get a new look at the item, alternative use, funny story and just let the new ideas jumble out together--then put them in order. Good Luck!!
