5. "Battlestar Galactica" (Sci-Fi): Sure, the third season may have been a bit disappointing compared to the first two, but then Led Zeppelin's third album wasn't as good as their first two either -- and we all know how quickly that became a classic. Baltar's trial, the standoff for the Eye of Jupiter, poor working conditions prompting a strike -- you can't say this year's episodes weren't eventful. Then there's the action-packed flashback film "Razor." Best of all, the last episode of the season ended with such a big bang that you just know it'll quickly push the fourth season into overdrive.
