I watch POV's. First of all, I factor in that almost all attractions actual experiences are way better than the POV. POV's don't do justice. My second reason is a bit different. Before POV's were widely available, I often found that on my first ride of an attraction, it didn't meet the too lofty 'expectations' I had of it. Example: That was the case with both JPRA and Mummy. Both excellent attractions, but my expectations were 'too high'. In subsequent rides, with more ''realistic' expectations, they've become two of my favs. So now, I'll watch a POV 'once', so that my initial expectations won't be overly lofty, and more realistic....and knowing the actual ride experience will be much better than the POV......I know I'm probably a bit in left field on that, but it works for me.
