Bah the second half of series 3 did it for me. I kept giving it a chance at the end of the 2nd series and start of the 3rd. It became unwatchable imo, bad scripts, shite annoying characters (any good ones, weren't in it, were under-used or dead) and generally ripping off the x-men cartoon/comic in a really bad way with the whole mutant registration thing. Matt 'Fat Keanu Reeves' Parkman, claire bennett, ando and hiro, daphne, all the least likeable cast in a tv show ever. Peter petrelli has to be one of the gayest main characters ever aswell, feck me grow a pair. John Connor in T2 is less of a crying homo.
