7. Saw IV
The franchise really went down after part 3. This movie is just boring. It has nothing to do with franchise. The characters are just so annoying to where you don't care if they live or die. Its just senseless gore and stupid traps.
6. Saw VI
This movie is just boring. Another film that has nothing to do with the franchise. Again just senseless gore and stupid characters that again you don't care I they live or die.
5. Saw: The Final Chapter
Now I don't hate this movie like others do, but its still not very good. The main character is just so stupid and annoying and can't help but hate him. The other characters are just bland and forgettable. I do think the traps are really cool and some of the best in the franchise.
4. Saw V
This is the best one outside the original 3. This movie continues the story from part 3 and forgets part 4. The traps are also really awesome in this movie and again some of the best in the franchise.
3. Saw III
This really should've been the last film in the franchise. The characters are very likeable and you actually want all of them to live. This is also the last film in the franchise to actually have continuity. The traps are great to.
I consider this to be a modern classic. It was a very original take on the Slasher genre also. And you would've never guessed the ending which was probably a shock to everyone. Most will put this as there favorite but I prefer...
1. Saw II
Saw II has always been my favorite. This movie isn't so much just traps, but more of these people killing each other. The gore is great in this movie to. And this is also one of the only films in the franchise to actually have a really good story. This is definitely my favorite, but as for the whole franchise I'd watch the first 3 and be done because the first 3 are really the only very good ones.
