Another good question for you (and the blog). Have their been any matches you awarded 5 stars to in the past, however, on later viewings you changed your feelings on the match(es) in question??
Sure, my opinions waver all the time. The TLC matches go up and down in my mind, the Razor-Shawn ladder matches, a couple of the Wargames matches...it really just depends what day of the week I'm watching and rating stuff sometimes. It's not an exact science at all.
