Half of the movie is just flashbacks of the first

Thats cause originally they was just going back and re editing the first movie and taking out all the gore and nudity, to make it a more friendly version since the first movie got so much criticism for that.

But the director demanded they make a sequel, so they turned it into a sequel halfway through editing it and filmed some new stuff with almost no budget, thats why the new scenes look so cheap and most of them took place in small rooms. So the reason so much of the movie is flashbacks is cause they didn't have the budget to film an entire movie, so they used the majority of the film showing flashbacks to the original movie as Ricky told his story.

I can't believe I wasted 35 mins and never skipped those scenes. I was just waiting for new scenes lmao.

saves time because anytime you want to re-watch the franchise, you can skip the 1st and boom - you've got yourself 90 extra minutes to do anything else you want
