I think most can agree that the second season of Dexter was easily the best of the series...but I think this was a classic case of peaking too soon. Tho its still a great show, the quality has been going downhill since that great season. They should've saved that storyline for a later season imo. This is what I would've done:
Season 1 - Same as it was.
Season 2 - Use the Miguel storyline. Have Doakes harass Dex throughout the season.
Season 3 - Make up a new story. Doakes is still around but have him back off of Dex for a while until he finds some new evidence in the end...setting up the next season.
Season 4 - Use most of the original season 2 storyline.
Season 5 - Use the Trinity storyline.
The following seasons would build off of the storyline of him nearly getting caught.
I still love the show, but I feel this would've been a much better way to improve and prolong the series.
