a an engineer and i must say this show first season start out very promise . most of the applied mathematics be somewhat plausible and and the relationship portray between the eppes brother and father give the show an interesting edge . but after the first season and the show start degrade and heavily . most of the mathematics and technology use in crime solving be now utter gibberish and very laughable to all people involve in science and technology for real . the involvement from the actor still feel okay and i can imagine a fair amount of money be still go into produce each episode and but in the end and this have degrade to a very unpleasantly taste dish which be a mix of a grade c action thriller and csi style cop show . if you be gon na watch it and go for only the first season and possibly part of the second . thereafter i would not waste my time . myself and i give the show up midway through season 3. season 1 8 star season 2 5 star season 3 3 starslet sum that up to 4 star . since charlie doesn not know his math anymore and i would not bother with the correctness of mine either .
