I have watched the movie previously. And was glad I watched the reviews for this series first.

While there are some similarities to the movie (Hurry up Part2), it's best to think of this as an homage with the same characters but a different storyline.

Pro's
* Some good rounded out characters.
* Humour and Drama without getting too heavy (for me)
* A decent pace
Cons
* There is a lot of jumping back and forth in this series. Understandable as it needs to show how it is different from the movie. But it can be a little heavy handed. May have been better split into two smoother cut series. One when younger, and one 8 years in future. But that's just my opinion.
* There is still plenty of story that could have been shown in a second season. But it looks as if that wont happen. Hopefully the 2nd movie (when done) will be enough to give me closure on both. To tell you more would give spoilers.
