I know, the first film made money so let's make another one and it'll make even more money, I do get how these things work.
But why can't they do it with better plots:
Picking up from where the last movie left off, Sarah (Shauna Macdonald) escapes the cave and seeks refuge at a local gas station, where she collapses and is rushed to a local hospital. Not being able to speak because of the horrific events that have mentally scarred her, a search and rescue team take Sarah back to where the horrible events happened to find any possible answers and survivors. However, whilst down in the cave...things don't go to plan as the group fight for their lives against the crawlers and find an unexpected survivor from the last film.
Why ruin a perfect ending to a perfect film? Why?!?!?
I'm off to write Citizen Kane 2 in which the butler remembers that Charles Foster Kane actually didn't say rosebud at all, he said 'chicken & waffles' which leads to a whole new investigation into his past.
