Near Greatness!
First let me say, this is the funniest thing I've found so far on Newgrounds, and I've seen some of the classic comedy movies here.
There are a few things I feel keep this parody from greatness:
* Many of the scenes drag on too long. Since this happens so frequently I assume it's intentional, but it doesn't add anything to the movie. One example is the eyeball feeling scene, where BF just stands there touching that eyeball for 10 or 15 seconds with nothing else happening.
* The jail scene at the end didn't sit well (no pun intended). Reading into it, I assume it's a jab at Firth's pattern of presenting a safe, tranquil scene followed quickly by a massively disturbing one. Regardless of whether it was planned or random, it didn't fit the tone of the rest of the movie (or the reset of the Banana Fingers series, for that matter).
* Cucumberdale's voice is really low and difficult to hear compared to the rest of the cast.
Regardless, I hope there'll be an EP. 5. How about having the armless BBQ dude visit the picnic? :)
