Genres for titles should be manually sortable

Ok, gotcha.  I did do a search for it before posting the idea and was surprised that nothing came up in the results.

There is the obvious subjectivity factor, but the way it's now sorted alphabetically the most accurate, predominant genres will often end up at the end of the list and then not even display in the first 3 included at the top.  And those will always be the ones that come later in the alphabet: IMDb Help Center: Genres.  B/c of this there will be many more films inaccurately labeled as primarily Comedy, Crime, or Action within their respective genres than Thriller, War, or Western.

To resolve this they could include a voting pop-up window w/ a button to the right of the "Genres" section (below "Taglines", similar to how they do for rating the title), with individual voting buttons next to each proposed genre to determine priority if the subjectivity is problematic.  Then the sorting could be automated.

if users could enter them without requiring IMDb approval, the automated voting system would determine which are most relevant by the user-base (based on the site's genre guide I linked above), and the genres that received too many down votes could be removed.

that movies should be able to belong the same genre as much older movies that are similar enough simply on account of the similarity, thus leaving genres to be somewhat defined by their pioneering constituent parts.

The object would be consistency.

@Ed Jones(XLIX):  Well, the Flat Earth Theory certainly wouldn't help in the case of your example, b/c anyone who believed it would have to agree that any film that involved space travel or portrayed the Earth as round would be science fiction...heheh.  There wouldn't be a way to prevent people like this from voting unless they made too many mistakes, and then their privileges could be revoked.  But such cases are a minority and therefore wouldn't affect the outcome unless more than 50% of voters voted up for Sci-Fi in that instance.  It would seem that more than 50% of members who are interested enough in a given film to want to vote on its genres would be able to do so in accordance with IMDb's genre definitions, especially if there was a note at the top of the voting section w/ a link to that Help page.  Either way, the end result would still allow staff to have the final say.

Sure, if staff/moderators and 20+ year members had the ability to view nearly all submitted films then it would be ideal, but I doubt that would round up enough people to make the system work.  The "how" part should be left for IMDb staff to figure out since they have the first-hand experience and knowledge from overseeing how the current system works.  Perhaps voting privileges could be included with a Pro membership and also granted to members who have contributed x amount of approved data, possibly adding weight from community forum activity/rank.  The amount of contributed data and forum participation being determining factors probably makes more sense than the amount of time since registering, b/c length of membership alone doesn't correlate to level of contribution, experience, dedication, interest, oversight, or knowledge.

IMDb could also allow members who submit a new film to the database to select the initial genre ordering, regardless of their voting status.  This alone would improve upon the default alphabetical sorting.
