The High 5 Flyer
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?
I completely differe here, I dont think they were forcely connected, though openion would obviously differ if you ask me I'd say they found an innovative way to connect sequels instead of actually trying to find a linear way to create a sequel( which probably would have ruined the experience). But then thats my take.
Also I am surprised you say that nothing has been shown/discribed about characters in SAW series, every character and the reason Jigsaw chooses to terminate him/her has been expleined in all subsequent series, with an in evident ending.
The way you have discribed SAW series, anyone can discribe to completely ruine even a cult classic.
Terminator 1 : Some robot comes from future to kill
Terminator 2 : Same robot comes again to save
Terminator 3 : same as above
Terminator 4 : None of the above
so now does that make Terminator series crap. Think before you actually put an example to prove your point (which you might actually have)
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.
I was merely Inferring to the level of interest that was generated to an extent that I could not wait to view the sequel for even one day.
