It depends on my mood sometimes I wants to to watch it on the tv and sometimes on the computer, but I often watch them on the computer since I use my computer more often than TV so it is more comfortable for me to watch it on my computer at my own comfort zone and enjoy. But sometimes a TV might be more enjoyable sitting far away with your popcorn and coca cola, watching some interesting movies.
I watch TV on an actual TV set. I have a 52 inch LG TV set. I watch movies on my computer but never watch TV on my computer. Sometimes I watch TV on my phone but don't watch TV on my computer. The internet service I have subscribed to provides free internet TV subscription accessible on TV, or mobile app. and I sometimes use the app to watch TV.
