Heroes = anticlimax, Sylar getting away? it had to end with him dieing for credibility as they just cannot use him for an entire series again, besides - what about this more powerful person? who knows what that entails? Hiro must learn all that stuff now he's gone back, no way he can be an awesome swordsman after 1 hour with Feng shui.
Lost = superb ending, charlie the hero, what a surprise - only a Brit (on an American show)
bring on season 4, i reckon they have 2 more seasons in it at least now - one where whoever comes and trouble flies and then one where they all reintegrate after they are rescued.
24 = good all the way through, early twists *wont say much more so i dont spoil it for lump* great action, good sub-plots and mythical ending

*edit* people also are uploading them to the divx site which is similar to video.google and allows huge files to be uploaded, though some do have audio coding problems and there are delays, if you can phase out of that and just watch whats going on, your sorted.
