@Dr. covenant is already on its way to making money. I believe it had the second highest sci-fi debut. It didn't have a big budget. Honestly with its smaller budget the film looks better than some films with a bigger bugdet.
One thing about forums they represent a small slice of the fan base. There are many people who don't bother with forums or social media for that matter. Some people just simply go to the movie and that's that and tell their friends or people they run into if asked.
Also the franchise as a whole eclipsed the 1 billion mark. Not too shabby.
Bottom line. I don't really care. I don't get any of that money. If they make movies I go see them. I spend my twenty bucks or whatever and get two hours of entertainment.
With that hat said I always enjoy when an R rated movie has success. It's important that R rated movies continue to be viable or stupid studio execs will think twice about allowing the R and push annoying pg-13.
