This literally feels like a compilation of (rightfully) deleted scenes from the other two movies. A very, very, very long one.
We know the end goal of this character, and we know the shtick: you never know when the real thing is coming, and the guys deranged. We did not need dozens of other barely tweaked iterations.
I liked the other movies because you really did not know who you were dealing with or what was ultimately going to go down.
Guess what's on the tapes?
Exactly what you'd expect.
If you aren't convinced this is a vanity project, consider this: do you seriously need an entire opening credits song with animation if it's just your 3 names shown 10 different ways with different titles?
I'm willing to say that this works really well if you've never seen the movies.
Then again, if you're subscribed to Shudder, you've probably seen them, and this is streaming exclusively with Shudder. My sense is they wanted this big name for an original and Duplass got to do whatever he wanted.
In summation, Duplass should probably spare us any more of this and directly unpack his deep rooted issues with videographers.
