Not convinced whether it's worth sticking with The Wire, Game of Thrones or The Walking Dead? Kevin Wu's Graph TV tool lets you see whether you've picked a winner. The site compiles a chart of users' ratings of TV show episodes on IMDb, plotting the rise and fall of ratings over each season.
GraphTV itself is pretty simple; type in the name or IMDb ID of any television series, and the site puts together a simple graph for each season of that show that charts the rating of each episode, giving you an optional trend line for the quality of a season or of an entire show's run.

It's easy to waste a few minutes seeing how your fellow TV watchers rate your favourite TV series; for older series, there's something fascinating about seeing the slow but definite demise as viewers lose interest. Just look at Happy Days for a good example of that.
