I liked it. Sure, it's not the best thriller ever and pretty generic (bunch of kids are on the run from some dangerous drugs criminals and have to try to outsmart them), but it's well done, the pace is pleasantly high, the story is solid, there's some serious violence, and the kids all get some background, just interesting enough to make you care for them. And just when things threaten to get repetitive, a second group of criminals joins the story to give it a new impulse.
The acting of especially Sara Waisglass is excellent, she's totally convincing as the intelligent and tenacious girl that's not to be trifled with. But I liked Stephen Kalyn too, he played impetuous, fun-loving Vince just as unpredictable and tiresome as it should be (and he's very cute to boot!).
I also have some tiny reservations as to the logic. Why would the criminals stand so much on catching Alex to lead them to the plane, when they could as easily have used the two kids that they already had captured. And how difficult could it have been to find that place themselves anyhow, the kids stumbled over it within ten minutes in the park!
But for the rest: well done and pretty entertaining.
