Taken 1 – ending is bothering me

Hey guys,
I have just finished taken the movie for the second time and this time the ending really bothered me.
I wondered in how far it’s realistically been portrait. I mean throughout the movie it’s Bryan against the mob and the corrupt police. However there’s never any ally or such.

In the end they take a commercial flight, come home and are picked up by mom and stepdad at the airport as they have just returned from a vacation.

Any one else bothered by that?
