Too short?

Sorry, I'm not able to answer 2 questions in a single blow.

The original cut was over 4 hours and I wanna see that cut.

what do you think was missing? probably the investigation and ending was too brief.

Another six hours would have been just about right.

One more hour, but just of a sick Indian woman wailing.
It did not have enough of that.....

I don't think it was too short as opposed to thinking that they could've shifted focus and kept the same energy and pacing with other aspects of the story. Instead it gets a bit bogged down and repetitive with what they focused on.

You’re probably just kidding but believe it or not I thought it surreal that in a 3.5-hour film we don’t get to see Ernest and Mollie’s children being born, making confusing for the viewer to ascertain whether the kids were theirs or the other sisters’. I spent a good half an hour guessing until it was made clear. I also agreed with those users that say the FBI’s work should’ve been fleshed out more.

Like I said, pretty unconceivable in such a lengthy film

Yes, I certainly agree. I saw in another thread apparently the last 10 mins was an actual show that took place, so I kinda get why they put it in, but would have been better if the movie was longer and we saw the outcome in 'real-time'.
