After episode one, I wasn't too sure about this series; I typically stick with a new series through the first season to give a fair assessment.
At first, I found the characters a little boring and predictable - though I continued to watch because it was... well, sorta cute. :) You'll not fall off the sofa laughing, but you will smile, and you will chuckle from time to time. I spent the first three episodes praying it would get better each episode, and it did improve as hoped.
In Episode 4, the show really takes off, much to my delight. Without giving away details, viewers are greeted with surprising moments and plot twists that finish with a "I REALLY have to wait a week!??!" feeling.
Imposters has the potential to be very successful, and if episode four is any indication, I think we're in for a treat.
