Dexter

I'm finally watching the series in order from the beginning. I've seen episodes here and there for the past couple years but I really got into it when I pulled a 9 hour marathon on New Years Day (starting the year off right!). I'm already a couple episodes into season 4, and although I know what's coming at the end, I have to wonder: Should I watch one a day and savour the next few episodes? Or should I just power through and become even more impatient for season 5? (Also, why is September so far away?)
*sigh* Oh, Dexter, how I love thee...
