I gave "#Reacher" a try on Amazon Prime and I just finished season 1. Here are my thoughts.

1. It was good clean dumb violent fun. Thumbs-up.
2. It's like "The Incredible Hulk" TV series but without emotions.
3. It's like the "Kung Fu" TV series but without moral quandaries.
4. It's like "The A Team" but without gold chains. There IS a van but it's a mini so it doesn't count.
5. It's not like "Gilligan's Island" at all.

TL;DR: Well worth a watch, just go in knowing it is what it is!
