Seeing a movie by yourself

Has anyone ever done this? I have the day to myself my son is at my dads til 5 and my hubby has classes til 3 so I was going to go see a movie by myself. None of my friends are available and I haven't gone to the movies in forever. Thinking of going alone but i've never done it before and I sorta feel like ill be judged which sounds dumb I know. Anyone else here go to movies alone sometimes?
