My best-friends boyfriend has Leukemia, I hadn't known him when he was first diagnosed, but he's had it for at least 2-3 years now and he still works, has fun, maintains a social relationship, has a prescription for medical marijuana, he did drop out of College because of his health-care expenses, but otherwise, he has a pretty normal life. So the two other reviews of people saying "When you have Leukemia, this.. that.." are true, but they aren't the case 100% of the time.
I've seen every episode of this show so far, and it's thoroughly entertaining, The girl does her best to live while she still has time, She highlights her motivations to fight cancer, the best part about it however, is the feeling it gives you after you're done watching it, it's one of those shows that motivates you, challenges you to do something with your life, seeing someone else struggle shouldn't be your motivation, however, it's a real eye-opener and it's definitely going to give you a positive, more optimistic mindset whenever you watch it.
It's kind of too early though, I'm hoping the writers take it in a good direction with such a sensitive topic.
Edit: I wrote this review when the show was still on Episode 2 or 3. Just got done watching S2 E8, It's got a 10/10. Thoroughly entertaining, very emotional (I must admit, it's had me in tears); Just amazing overall.
