The acting is SO bad in this. But the writing is great (even the character/technology tweaks) and the film crew was proficient enough to make the talking, pretty mannequins enjoyable.
The movie adaptations were garbage, not because of Tom Cruise's height, but because they turned Reacher into a Mary Sue. As indestructibly physical the character is in the novels, he has handicaps and weaknesses. The movies made him an urban stunt driver that could blend into a crowd while the entire police force is on the same city block.
The novels' Reacher also has extensive experience in specific circumstances. When the movie version CHOSE to walk into the center of opponents encircling him... Peter Dinklage's acting skills couldn't have made that character believable.
