A lot more believable than the Tom Cruise movies, but it was annoying that Reacher — now played by Alan Ritchson who is as big as a house — kept being close to having his ass whipped by diminutive bad guys two thirds his size and half his weight.  In the books he never comes close to having a hard time beating half a dozen big guys at the same time.  [minor SPOILER] In one scene Reach is repeatedly smashed about the ribs and the side of his face with a large crowbar, but when he eventually prevails he shows no sign of the broken ribs and dislocated jaw he should have had.  Lee Child makes his obligatory cameo in the last episode (I think).  With all the money he must have made from the books you'd think he could afford enough meat pies to put some flesh on his bones.  He looks like a skeleton.

 

True. In the books the fights describe how he uses the opponents force, direction and speed against them - by simply turning and lifting the knee, or dodging at the last minute, spinning and hitting someone's heads.

In the series, he gets kicked a lot.
