Smithereens v. Rachel, Jack and Ashley too
These two have a very interesting contrast.
With Smithereens I feel that the central idea was weak. Guy has a car crash thanks to his addiction to social media and kidnaps an employee. I found this idea a bit weak and cliché. Yet, the entire episode was elevated thanks to the great writing and the awesome acting.
With Rachel, Jack and Ashley Too I felt the opposite. The concept of Ashley Too is interesting, but the entire episode was botched due to lazy writing. The part where the girls outsmarted the guard felt like something of a Disney Channel original movie. Overall, a wasted opportunity.
