The problem is, Star Trek screwed itself with its obsessive overuse of time travel as a plot device. There was always a kind of pride in Star Trek's effort to be a projection of where science really could eventually take us, but time travel has never been anything more than fantasy. It isn't compatible with any understanding of the universe today. The only thing that comes close is the multiverse fantasy, which isn't even technically time travel, and is itself just an extension of the hard-on people get when they hear the word 'infinite'.
Time travel isn't something you just build a random plot off of.
Star Trek has also had supernatural kind of things like Q, creatures that live in the vacuum of space, plus speculative parascientific concepts which have very little real science behind them, like psychicsm, telepathy etc.
The problem with time travel plots from my point of view is that its easy from any bad writer to come up with a 'profound' sounding time travel plot , just create an anomaly here, and a paradox here. Profound! Really clever time travel plots are rare.
