"Because It Doesn't Require Any Batteries!"
Well, I have to say, that was fairly entertaining. First and foremost, I have to give you kudos for actually coming up with 10 things to do with a dismembered arm. Before I watched the movie, I tried to see if I could come up with 10 myself. And, alas, my creativity failed me.
The movie itself is well done; the music (well, what music there is) was nice and fit in well, and the animation was superb. I like the way you animated Barry; he has alot of interesting facial expressions, and tons of just quirky movements. I can tell alot of detail was put into it.
The voice-acting was hit or miss. I'd tone down Barry's voice next time. Sometimes, his accent is absolutely hilarious. For instance, the way he said the batteries line (quoted above) just made me crack up. However, more often than not, I found the voice overly-annoying, and it grated on my nerves, almost to the point of distracting me from the flash. I think if you just lowered the pitch a little, or made it a little less strong, I'd be fine. Just my opinion though.
I also thought that the distribution of the jokes took away from the flash. See, you really get the funniest uses out of the way at the beginning of the flash, so that when you get to the final six (with the exception of the lamp), I'm just not laughing. I think its generally a good idea to save the funniest joke for last, or at least have them equally distributed throughout the flash. I don't know; I just felt all the funny jokes were in the first couple suggestions, and then it just falls flat from there.
Still, a great submission. I enjoyed it :)
