I'll answer the OP's question first. I don't see any harm in any of the things on the list, unless they should be a cause of sin for the person. E.g., someone who has a weakness for involvement with the occult might have to choose to avoid Harry Potter because it tempts them. (Most people can read Harry Potter and enjoy it without worrying about any kind of temptation, other than the temptation to spend a ton of money on Harry Potter paraphernalia!).
I would respectfully question whether someone who is involved with "fandom" (for lack of a better word) for all these things is really spending their time wisely. Fandom is very time-consuming--I consider myself a "fan" of several milieu: FIGURE SKATING!!!!, Sherlock Holmes, Dark Shadows, Robert Patrick (actor who played Terminator 2), Sting, Taylor Hicks. It takes time to watch or read about my fan interests, and it also costs money. I honestly don't think I could continue to be a fan of these things and add more things. I probably should drop some of these and put it all into figure skating (but the figure skaters aren't as cute as Robert Patrick!).
Most of us have only a few hours of leisure time each day:
8 hours of work or school
6-8 hours of sleep
1 hour of "personal grooming, bathroom, and hopefully some physical exercise
1 hour of some kind of religious devotion (Mass, Adoration, Bible study, prayer, etc.)
1 hour of "chores" e.g. driving to places, cooking, cleaning, car maint, pet care, etc..
1 hour of eating
This is a total of 18-20 hours of "necessary" time that most of us can't get out of. That leaves about 4-6 hours for each person each day of "leisure" time. Wouldn't that list of shows and movies and other media experiences take much more time to pursue than 4-6 hours each day?
I suppose someone could cram it all into a weekend. Or people can "double up" and eat at the same time they watch TV, or do their personal grooming with a TV in the bathroom. Or many people shorten their religious devotion to only an hour a week. And some lucky people can watch TV/movies while they work or while they are in school.
But yowza, people! Is that any way to live? It's not really a life--it's immersing yourself in non-reality.
I will say, though, that one of the reasons I get involved with fandom with all the things on my list is spending time with other fans.
I suppose another possibility is that someone who is disabled might have a lot more time to spend on these kind of leisure activities, and I can understand that. But it really depends on the disability. I know a lot of "disabled" people who accomlish more than I do! :o
Anyway, I think we should consider how we spend our limited time here on this earth and invest ourselves wisely. I struggle with it, too--e.g., right now, I'm sitting here eating Ritz crackers and cruising around CAF! But I have an excuse--a bad cold. :(
