Good, Not Great
This is a decent flash. Not the most fantastic, but good enough. The 'WTF' factor is an okay way of going about getting a few laughs, but it's definately not the pinnacle of comedy. The ending was a bit abrupt, but it adds more to it than it takes away.
Funny thing about a review before mine, Ebaumsworld (Eric Bauman) has a quite a few people rallying against it(him.) Including Newgrounds itself for the very same reason(and a few others) that Dave is being accused of.
You know. Plagiarizing.
It's FUN to learn!
'Cause knowledge is power!
