The Wire is probably the best TV show I've seen in recent years. Its about Baltimore Police trying to control drug dealers in the city. If u like such kind of shows revolving around corrupt police officers, corrupt government officials, drug lords, gangsters, betrayals and all......this show is the best. The cast is nice as well with names like Idris Elba, Aidan Gillen, Dominic West and Lance Riddick. If u have seen Suits and noticed how sometimes Mike Ross says "shiiiiiiiiitt" this is in reference to Wendell Pierce's character who says shit exactly like this and who played Rachel Zane's father in suits! However the show is quite long, most of the people will find it boring during the first few episodes but once it picks up the pace, damn u'll be completely sucked into it. I would definitely recommend it (Y)
Dexter on the other hand is not as serious as The Wire, its about a forensic specialist who works in Miami Police and at nights he's serial killer but since he's a forensic expert he can cover his tracks easily. The first season was nice, the next two seasons sucked but then came the fourth season when he faces off against another killer called the Trinity. Damn shit got serious then! I'd say only after watching the fourth season this show will get your interest. So its kinda like 50/50, survive the first 3 seasons to really enjoy it.
