I would like to explain to you what makes this show worth watching.
There are 3 main reasons.
1. The plot: to sum it up in one word "amazing" How the creators came up with this idea ill never know but it is great, a totally unique and might I add awesome idea for a TV show, The mix of the drama and the comedy in the show is just stunning major kudos to the writers
2. The characters: Every single character on this show is great. whether Im watching Casey lay out some serious fighting skills, or watching Captain Awesome be...well, awesome it always has my attention
3. The relationship between Chuck and Sarah: Last but definitely not least the element that most makes the show worth watching. Their chemistry rivals that of another great TV couple *cough* J.D and Elliot *cough*. They play off of each other so well that it makes me really believe that Yvonne Strahovski really is a super sexy C.I.A agent and Zachary Levi is just some "nerd" that happened to land the hottest women on the face of the planet in the most bizarre sort of way. I love Chuck and Sarah.
So to answer my question, Yes this really is the greatest show currently on television, I haven't been this obsessed with a show since I first set eyes on Scrubs. If you have not seen this show or you've seen a little and are skeptical about it, Just watch it you will not be disappointed.
