Let's get this straight, this is not in the same league as "The Raid" (to name a recent entry) or "Chocolate" (a bit older one and obviously not the one starring Johnny Depp). But it does what it says on the cover. It delivers on the action/stunt part. Now if that is enough for you, you might be able to oversee other flaws this movie has (especially in the story department).
So while we have characters returning (Tony Jaa's being one of them, the Elephant one other one), the story is completely forgettable. It doesn't really make much sense, something conspiracy or other. But that should not be important. It may take a while, but when the action kicks in, it does so with a bang (and a "vroom" or two). There are some very high risk stunts here (some outtakes can be seen in the credits after the end of the movie). Ask yourself if that is sufficient and act/watch accordingly
