Almost all time-travel story science falls apart (or paradoxically eats its own tail) if you look at it too closely (or from too many vantage points). It's the nature of the beast in my opinion. Those who strive to make their time-travel science "more plausible" usually do so at the expense of their own story. That's why I usually prefer the time-travel stories where the author doesn't waste a lot of time trying to sell me on their "science."
