I've already seen 11, 12, and 13 that last time I watched any of the movies over ten years ago. It's only 10 and 14 that I never got an opportunity to watch (even though I truly was interested in watching 10). The only reason I never got to see 10 was because that was back in the day when video rental stores were still a thing, and 10 was the only one they did not have available on that day when I got to see the other movies.
But like I said, I'm a little too busy with other things right now to take a look at these movies on Prime, so I just hope they will still be available for a while until I can finally have an opportunity to set aside enough time to watch these movies.
