In a movie like Deadpool, he effectively conveys emotion even as he's mouthing a one-liner that elicits laughter and probably makes the viewer cringe at the same time.
That skill or talent—whatever you wish to call it—must be why he stars in this flick. In fact, the movie may have been built around him for that ability.
Six individuals from all around the globe, each the very best at what they do, have been chosen not only for their skill, but for a unique desire to delete their pasts to change the future.
6 Underground is one action scene after another, stitched together with Reynolds and his one-liners.
The opening car chase sequence is...well, let's just say some stunt drivers got a big payday from the lengthy scene that left little room for charaterization.
In fact, characterization was tossed in as an afterthought later in the movie, rather than making it a way of letting the viewers get to know the characters and learn why they were doing what they were doing—which was preposterous in the extreme.
Rather than creating a story about a character/hero that the viewer could like and root for, the movie depended on Reynolds's onscreen personality in similar movies to make him, as hero, appealing to the viewer.
Sorry, Mr. Reynolds, Mr. Bay, and the other talented cast members. Thumbs down from me. This movie will probably appeal to people who like loud crashes, mind-numbing action sequences, stunts of all kinds, and disengaging the brain while watching. The rest of you can probably find something better to do with 2 hours and 8 minutes.
