I was watching a movie on the Roku Channel. Because the channel is free, it's got commercials. The more I watched, the longer the commercials got. At some point I gave up and turned it off. The movie is 132 minutes long and there are 10 stops for commercials. The last commercial was 2 minutes.
I'd rather pay for a subscription than watch commercials and I will definitely not pay for a channel AND watch commercials.
