TVLine's 2013 in Review, Part 1: Best and Worst Series, Episodes, Newcomers and More! Plus: Most Improved & Underrated -- 30 Titles Total!

The bulk of 2013 may already be in the rear-view, but at least in television terms, it’s been an unforgettable trip.

To celebrate a banner 12 months that strained our DVRs to the breaking point, left us clutching our couches in suspense and had us laughing loudly enough to occasionally alarm the neighbors, TVLine presents Part 1 of our Year in Review — including our selections for Best and Worst Drama and Comedy, Most Improved Series, Guiltiest Pleasure and even the Cancellation That Hurt Us the Most.

So, click through the gallery below for our picks in 30 key categories — then come back on Friday and Saturday morning for Parts 2 and 3 of our 2013 wrapup. And, as always, when you’re done, hit the comments and tell us what you think we got right, which selections had you crying “blasphemy!” and which series you think we egregiously snubbed.
