A tribute to Chekov actor Anton Yelchin.
No outright comedy, TVH was an outright sitcom and TFF trying to pander with more of the same was a flop. Comedy in later movies was also a mixed bag, especially when aimed at the audience rather than letting it flow naturally.
Something other than a revenge trope, unless they can really pull it off. STB managed it. STID almost managed it... STVI made it truly spectacular.
Keep it nowhere near Earth and don't have ships go there. Let's do a count:
- Involved Earth
- Didn't involve Earth
- Barely involved Earth, mainly as a plot setup
- Involved Earth royally
- Didn't involve Earth
- Barely involved Earth (only for peripheral plot setup)
- Didn't involve Earth
- Involved Earth royally
- Didn't involve Earth
- Involved Earth only because the writers got bored with every other magical and implausible or dumb idea so why not chuck in Earth for no reason just to make it even lamer?
- Involved Earth royally
- Involved Earth royally
- Didn't involve Earth
Forget even-numbered nonsense, the ones that don't wallow in Earth are the best.
A low fewer easter eggs/meta references/etc or using old characters as crutches. Re-viewing STID recently, it's honestly a very solid and strong enough a film, uses Earth reasonably well (though could still have worked without the grandiose f/x of the ship crashing on the planet, another overdone trope and GEN did it best anyway), didn't need "Khan" whatsoever to gain and maintain interest, or the hideous redo of the fan-favorite yell of "KHAAAAAAAAAAAAAAAN!" to have been truly great. With better handling, the "magic blood" could have been made to work. (And to be fair, their playing it straight, letting Spock yell it would have been poignant if it worked, and not doing a 4th wall-break send-up ensured it it wouldn't be received any worse if it didn't work. )
Don't kick heavy machinery to re-align the engine part, not even the Incredible Hulk has the strength...
