The plot is the same in every single one of these movies. It's just a different scenario. The first one is a plane, the second one is traffic, then a roller coaster, race car track, and now a bridge. A disaster happens, the main character zaps out of it, finds out what's about to happen and saves people who will later become death fodder from dying.
Then one dies one by one in the order of how they are supposed to die and our obnoxious heroes must find a way to trick death.... in the same way as the other movies. Really, it's the same film over and over again. There's not a whole lot of substance to be had, other than the fun in the kills. That's it.
There's not much to say other than if you like these kind of films, go see them. The formula never changed, and honestly, you come to see the inventive kills and that's really the fun. The bridge scene was really well done. It's actually amazing to see from the characters' eyes as the bridge collapse is pretty awesome. Some of the kills are nail-biting and the payoff grossed even me out.
It's not a bad film, and it's a lot of fun as long as you turn your brain off. It just doesn't separate itself from the rest of the Final Destination movies. Also, the very end of the movie shows kills from each of the Final Destination movies. Why did they show that? It makes you not even want to see the previous installments. Nice going, filmmakers.
