Some are already pointing out how different "Beyond" looks compared to its direct predecessor. That film, 2013's "Star Trek Into Darkness," has been described as brooding and self-serious, whereas "Star Trek Beyond" promises something lighter and funnier.
Even those comparisons belie the wider trend in Trek that fans have been lamenting ever since Abrams took the helm. Abrams has already made "Star Trek" lighter and funnier, much to the irritation of longtime viewers. The original was "too philosophical," Abrams has said — explaining why he turned "Star Trek" into simply a mere action franchise.
For Lin now to push that even further just tells you how far the series has departed from its roots. The older "Star Trek" was slower to violence, quicker to introspection, more deeply embedded in its fictional universe, less devoted to knee-jerk emotional appeals. It had complicated characters, powerful narratives and grappled with mature issues without being pedantic. These qualities are largely lacking in the newer films.
But let's turn back to the "Beyond" trailer for a second. It appears to show the U.S.S. Enterprise being ripped to shreds by alien spacecraft, forcing Kirk and his comrades to flee the ship in escape pods. Incidentally, "Star Trek Into Darkness" also saw the Enterprise getting crippled by another enemy vessel, causing Kirk's ship to fall dangerously into Earth's atmosphere and nearly crash.
That the Enterprise basically keeps getting destroyed in these films has got to be a metaphor for the franchise itself — ripped apart and put back together, ad infinitum, looking less and less like its former self each time.
