Most of those are tech geniuses, but a few are just smart in other ways like reading people, or in science. And some are more serious than others.

X-Files (Silly ending at end, glad it's back soon, 6 shows i don't get it) Blindspot is good so far and Arrow just love it.
Big Bang Theory, Scorpion, NUMB3RS, must of the detective shows that are currently running.
I also suggest non-fiction shows. A lot of the PBS educational series have personable narrators.
Well Lost is good tho the ending isn't the greatest, Arrow, How to get away with murder, supernatural, Medium, Forever, castle, jorneyman, doctor who, American horror story, scream queens, oh and almost forgot Being Human, true blood, dexter bout it I've heard breaking bad was good as well, also if your looking for a new show to watch that show lucifer looks pretty good the pilots avaliable online if you want to see if you like it
Arrow has Felicity.
Warehouse 13 had Claudia.
Fringe had Astrid.
Mr. Robot.
The story is about a guy who works at a cyber security company. On his own time, he uses his hacking skills to work as a vigilante, hacking criminals and then providing the police with the information anonymously. He is noticed by a hacker group called F-Society. They recruit him for their mission to take down a company called E Corp. It controls most of the debt in America, and they plan to hack in and wipe their servers so that all the record of the debt will be lost and all those people will be free of debt.
This is the only show I've seen (including all the ones people have already mentioned) that realistically shows hacking. Hacking isn't like in the movies/shows where they hit a couple buttons and then suddenly they've hacked the FBI. It doesn't work like that. The show does a great job of making it more realistic. Showing that it takes time and planning to prepare a hack that big. It's a great show. You'll love it :)
Fringe (on Netflix/Amazon) Is a great show with awesome and unexpected twists. It is kind of like the X-files in genre. There is a Strong-willed female detective, lovable mad scientist and plenty of other character that make the show great. I couldn't get enough of this show and wished it never ended
Sherlock, How to get away with murder, bones, CSI? I hope this helped.
