TM2YC has done an excellent job fixing the major problems with "Into Darkness," including some I hadn't thought were fixable (such as Kirk's demotion and Uhura's characterization). The FX work he's done to get some of these changes to work is nothing short of flawless, and I noticed no audio issues on my 2.1 soundbar setup.
Narratively, I still have my issues with the film, specifically Khan's magical healing blood and the "Wrath of Khan" remake B.S. with Kirk that makes the magical healing blood necessary to the plot, but the way it's been edited here makes it all much more palatable. And I have to say, bold (but very smart!) choice in cutting Nimoy from the film - I wouldn't have thought a fan editor would have the guts to do that now that he's sadly gone, but it is absolutely the right choice for this film.
"Star Trek: Vengeance" now it sits comfortably alongside the theatrical ST09 and Beyond discs on my shelf, forever replacing the theatrical cut with no reservations whatsoever.
Star Trek: Vengeance takes the already pretty good but very flawed Star Trek Into Darkness and makes it genuinely great, up there with the other two Kelvin Timeline entries of the franchise. The plot feels much more clear, without any unnecessary distractions like Carol Marcus' striptease or the more fan service-y bits and pieces. The changes I appreciated the most are incorporating the deleted scene explaining why Carol has a British accent and re-arranging the Spock hunting Khan bit where he's now chasing him to get his blood as opposed to wanting revenge. While I did enjoy Leonard Nimoy's appearance and the relationship tensions between Spock and Uhura in the original film, I had no problem with them being cut out for this edit as a means of keeping the story focused. This feels less like a Wrath of Khan wannabe and more like a standalone strong Star Trek adventure, and for that alone, I got a real kick out of this edit.
This is an excellent example of making a disappointing movie better. I never hated "Into Darkness" since it's at least entertaining for the most part. TM2YC's fanedit removes the absolute worst parts and tightens the pacing throughout while retaining the core spirit of the film. It's still a cheesy flick with a horrible villain and contrite writing, but hey no it's no longer sexist and dumbo.
I think this fanedit is wonderful.
I really liked the changes TM2YC introduced and implemented - such as cutting the demotion/promotion subplot, the striptease, Uhura's drama, and many many others.
The plot flows beautifully now, without going off on tangents. Well done!
One thing I wish were possible is a complete removal of lens-flares. I know they're one of JJ Abrams trademarks, but they can be very distracting...
Anyway, long story short - I really love all of TM2YC's fanedits, and wish I was that skilled in fanfixing films.
