I thought it was a bit "lame".
Now I'm no expert in what it's like to come out of an 18-year long coma, but.............................the lead character seemed to adapt to her "new" world/surroundings very quickly, i.e. she didn't seem to be curious as to how her neighbourhood had changed or the new types of cars, technology, etc that she was experiencing.
Also (when talking to Pete at the cafe), she seemed to think that she had just woken up from a nights sleep, but didn't seem curious as to why Pete looked completely different, i.e. older!
Not sure if I'll watch the rest of the series.
