Sitcoms, drama, whatnot.
Personally, I mostly prefer sitcoms.
The series Ive followed:
*Lost (all episodes, next comes 21.jan.2009. I think season 5 starts?)
*Prison break (first 2 seasons, after that i didnt like it anymore)
*2 and a half men (6th season is running atm, ive watched 2 seasons)
*big bang theory (2nd season is running atm, ive seen all episodes until december 2008, i think 1 episode is out now)
*my name is earl (4th season is running, ive seen all 14 episodes what are shown, next comes this week)
*top gear (12th season running? seen most from TV already, just catching up by watching some episodes from computer)
*mythbusters (6 seasons are out? anywho, seen most of the series from discovery, just cathcing up on episodes i didnt see)
*brainiac (saw 4 seasons. Then richard hammond quit and i dont want to watch it anymore).
*persuaders (mmmmm young james bond, seen all episodes)
*The office (just some episodes which ive seen from tv, looking forward to have some more time to watch a season or 2 in one weekend =))
That pretty much covers the series i have in my computer, which means i have further interest in the show, than just catching it from tv at random times.
Now you, reader, could suggest some series, whcih you like to watch.
Personally my top 3 would be (in random order):
lost, my name is earl, the office
