I imagine the writer of this series saw Point Break (the original with Keanu Reeves, not the cheesy re-make) and thought it was awesome, then went about trying to write this series. Unfortunately it doesn't really hit the mark. It's not terrible, but it lacks the panache and effortless cool of the movie.
The main downfall is most of the characters are fairly unlikeable crooks, who act like big children when they're not committing crime. Even Josh, who is realitively innocent, lacks the charisma to make you care about him. So ultimately it's combination of extreme sports action (not particularly well done) crime action, and family drama that's difficult to care about.
For me it's worth 2.5 stars really, just about watchable if you've got nothing better to do.
