Movie Critics

I don't understand Movie Critics. I went and saw Alien Verus Predator today and I give it 4 out of 5 stars. I thought it was great. It was action packed and get my attention through out the movie.
By the way I am highly upset at AMC Theatres. I had a coupon for a free ticket and they would not honor it. They said they were not on the program. However, they could of still got there money. Just makes me mad.
