A little disappointing.
I'm a massive fan of the first two Everyday Adventures of Steve, which I consider the peak of humour. Though Steve 3 is longer and filled with more intense action, the jokes and puns took a severe dive, though there were still a few good ones in there.
In terms of music, you made some excellent choices there, but as the voice acting (while your effort is noted) was just a little hard to buy. As for the animation, you've noticably stepped it up a notch which is great to see, but all this doesn't quite make up for the traditional Steve we (or at least I) know and love.
I was hoping the ending would redeem the previous nine minutes, but it was highly anti-climactic: I was expecting Steve to demand a promotion or free access to porn or something similar, but it just sort of cut off. That said, the Megaman credits were pretty cool.
All up... Though longer, the humour (what I feel is the winning characteristic of the Steve series) took a pretty serious dive leaving the whole movie a little subpar. Looking forward to Steve 4 and a renewed supply of humour.
