I guess over the years they've gotten very good at faking it, although all those vehicles destroyed were not faked, I don't think. Other than that the action is pretty spectacular, but the plot needs work, as do the characters.

They tried to give each a backstory, but the second woman was pretty anonymous by the end. She didn't get to do much of anything, except treat a gunshot wound in a fast moving car at the beginning. I don't recall if she got a backstory.

For a plot, they go after their #1 pick for their sleazebag list and the whole film consists of their efforts to thwart him. What about the guy at the beginning? Or any of the others? For sequels perhaps?

I suppose there will be some. Ryan Renolds does a pretty good job with his role, so I expect they'll like him back. Same for most of the others. But they can always be replaced with new "dead" members.
