I am a fan of crime dramas, but found The Inside extremely disappointing. To be fair, I may be spoiled by Criminal Minds, but stacked up next to the latter, I found The Inside shallow and unsophisticated, with uninteresting characters and boring cases. Actual profiling is usually nonexistent and when present at all mostly meaningless nonsense. Even worse, especially for a crime drama, I found outcomes extremely predictable (maybe because of my "training" from Criminal Minds.
If you enjoyed The Inside at all, I strongly recommend you try out Criminal Minds. Even with the recent departure of Mandy Patinkin, it has far more to offer than The Inside.
