i watched the first season and started on the second but then everything just went mental, just like every other american show and they take the whole shows to the limit - and even cross it.
prison break, heroes, lost are all the same and probably true blood will also get in the same cathegory anytime soon.

the only shows that can take 2 or more seasons and still be worth watching are the humour ones. like friends, how I met your mother, scrubs and whatelse.

they should stop making these super long series and just try and keep it down to a maximum of 2 seasons...

in my opinion. =)
