You will I am pretty sure. Even I was only able to follow the first two easily and had to rewatch 3 and 4 to get things right, and when I did I was blown away by the innovative connectivity they had shown
Would u mind if I say, those are forced connectivity.
U show a character in part one. Nothing much has been told about him/her. Not much focus is on him/her. May be in one scene he/she ws shown filling a glass of water from a cooler at an incident spot or walking by another incident spot.
Now, when u sit down to make sequel, u really don't have a story, u have the fortune and fame infront of u, and u want to encash it again.
U do a research (good research though) to find any character which is not explored (exposed) in previous part.
U choose two-four such.
Do a more research whose appearance was close to incident spot in first installment and then u sit down to create a story around him/her.
SAW1: He's a psycho
SAW2: A bit on why he's doing such things
SAW3: same as above
SAW4: same as above + why he's psycho
SAW5: Now to stretch it, u put a flashback to him. Its done by every film. Watch any South movies. There every movie has to be of 3hrs. So, to stretch the length, always the hero or villain has a flashback. And, obviously u put a partner with him, he had partner previous also, but this time u r told he had another one. So, if he had two partners, why not three, why not it was someone else who was controlling him?
From now expect every kind of plot twists in it.
SAW is the only movie after Back to the future where in I was compelled to get the next part immidiately and go for it.
Back to the future part one is good.
But the second part is incomplete without third.
For this movie, Part1 doesn't raise a question for a second part but part two sure asks a third installment.
If, u watched the trend of sequels closely, u would find a pattern.
Tremors part 1: One animal is left at the end of the movie. (result more sequels)
Jurassic park: Dino eggs left at the end of the movie (result, sequels)
Terminator: Never ends at the end (calls more sequels)
Then there comes those movies which became immensely famous due to some particular character.
Matrix (there had to be sequels, why would u leave such a popular brand)
Mission Impossible
Police Story
After "Shanghai Noon" there had to be "Shanghai Nights"
Bourne series
oh, I can go on in this topic.....
/offtopic, how did u guys watch SAW6 and PA? Is the DVD out?
