I've tried watching Prison Break, Covert Affairs, Supernatural, Suits, Lie to me, Sherlock Holmes, Lost, Nikita, One Three Hill, Awake, The Game of Thrones, Merlin, House, Six feet under, The Menatalist etc. Most of them are friends' recommendations of what they like but only few of them seem interesting to me.

First of all, the ones that I enjoyed most are Prison Break and Lost for they are extremely engaging, dynamic, the plot is genuine and clever and the unusual places and situations help me take my mind off anything while watching.

Secondly, I also enjoyed Lie to me, The Mentalist, Sherlock Holmes, Awake and Covert Affairs, but I couldn't watch more than 5 episodes from each of them because I got bored and I even if they are clever and witty, I still don't feel like watching them again.

Thirdly, I liked The Game of Thrones and Merlin, but again, they didn't catch me. I think the first one is a bit too cruel for me and the second one is actually quite good, but I watch one episode a week or two weeks. I'm not patient enough to see more of it.

As for the rest of them, I consider them either a waste of time or unappropriate for my tastes.

So, I'd like to know if you happen to know some WITTY, CLEVER and engaging series that will keep me on the edge of the seat! Thank you!

I loved prison break and lost so I am going to throw out a few others I enjoyed as well...
Heroes, Dexter, Grimm, Eureka, those are just a few, check them out I'm sure you'll like at least one of them dexter for sure
