there is no reason this movie or any other on steam that requires internet should take up any hard drive space if I can't watch it offline. store page says you have to be online to watch the movie. when I watch online on netflix it doesn't take up storeage on my hard drive. in fact when I watch stuff on netflix I can download it and watch it offline. on amazon prime I can download shows and watch them offline. why cannot I watch this movie offline? either catch up to the times or lose out on sales....
