This is BYUtv's first attempt create a family series on a limited budget, so I was concerned it would be cheesy or poorly done. That was true at first, but then they learned from their mistakes, and things got really interesting...
Season 1: 5/10 stars. A few good moments. Persevere.
Season 2 (first half): 7/10 stars. Improving. Important changes in scripting and acting make a *big* difference.
Season 2 (last half): 8/10 stars overall. Added some big name talent, impressive script developments, characters start to come to life.
Season 2 (finale): 10/10 stars. Brilliant! They are hitting on all cylinders now.
Season 3: Can't wait to see. I feel like I *must* watch it.
You'll have trouble understanding season 2 if you don't wade through season 1. IMO it was worth it. Think of it as an example of "agile" business methods (like they used for the iPhone, etc.)--get it out there quickly, learn from your mistakes, improve rapidly based on actual feedback.
