The concept is intriguing and then some. The main reasons for watching this mini-series were the genre (action/crime) and the rather short running time per episode, with the latter meaning you could finish this in a single sitting. And given that it has enough intensity and flair to work, Dealer turns out to be a gripping and entertaining affair. This mix of found footage with the action genre is something we don't see a lot of times, and thus another reason why the experiment pays off.
It is indeed interesting to note how much the makers manage to achieve in terms of character development and plot within such a short duration. Performances are all top-notch, and the visuals are pretty gorgeous. Colors are beautifully used, and the action sequences are all very impressive. The switching between cameras to deliver action filmed from different angles is uniquely done, especially in a vivid car chase sequence.
Some might find the camerawork too jarring at times, but this is just how the show was meant to be: like a recovered footage. I personally love movies and shows filmed in this format, and hence this is a big draw for me. Also, the story is pretty gripping with enough twists and drama served along with the gritty action sequences. All in all, this is a pretty solid series for its genre and style. Recommended especially if you like crime action dramas and would also love to see how something like that goes down in the found footage format.
