General discussion + *spoilers* (seeing as there are so few threads yet)
Just watched this movie and it was great. Much like the whole Terminator series it kinda *beep* with your head though! I guess they all ended up at the cabin as Samantha's father's death was the catalyst that triggered all their future deaths.
I like to think that Tom does get conceived because Kevin was never really the dad.
That is my theory anyway.
