Its really super easy to time travel in the Star Trek universe (some movie spoiler)

I read some reviews with people complaining how easy it was to travel back in time in this new movie. I agree they could have done a better job explaining it than Spocks flashback. But its not like they havent done this before.

TOS established that you can exceed warp 10 around a star and go back and forth in time as you please. They confirmed this on TNG to.

Go jump through the Guardian of Forever and go you can travel in time.

Get you one of them Bajoran Time Orbs and you can just think where you want to go.

Theres always future star fleet and their damn Time Ships always popping in and out.

In TNG theres like a 1 in 3 chance that whatever sub space anomaly they run into will have a future or past enterprise popping out of it.

The wormhole aliens in DS9 could go back and forth in time whenever they want.

Theres always someone or something messing with time travel in the Star Trek universe. The time travel plot in the new movie wasnt that bad.

Every series has either an alternate timeline or a parallel universe. The TNG episode "Parallels" has literally hundreds of Enterprises, each from a different universe.

In the TOS episode "Assignment: Earth", Kirk and crew go back in time to do research.

Anyone complaining about the time travel in this movie isn't that familiar with Star Trek. It's used as a plot device all the time.
