I like this show and I do think it is fairly as realistic as possible. For one if you are a fugitive on the run you usually don't get time to grab cash first or pack or buy burner phones for you and friends/family. The most unrealistic part is that the fugitive has an ATM card to use. A fugitive on the run will need to, at best, work for cash or at worst...steal or rob for it. I think most fugitives would know better than to try to contact friends or relatives. And real fugitives on the run probably aren't going to get much help from strangers since they don't have a camera crew with them.
I also think that the explosion of social media in the last few years means that if you do go on the run and you have used social media it is going to be fairly easy for law enforcement to get an accurate profile on you and get access to those accounts along with an extensive list of family/friends. I mean if you are actively running from law enforcement a judge is going to give them almost anything they ask for.
And yes I am rooting for the fugitives too but I don't think many will succeed but I think one or two will.
I have watched both seasons of the UK version. I will post more about that with the spoiler tag...and there are spoilers in there.
