Who's on the other end?
I definitely like the concept. A guy finding a "chat bot" online that may or may not be human. This animation feels too incomplete for me though.
For starters, he clicked an online ad. Who does that? :P
The music felt a bit too dramatic, as if to force a feeling into me that I wasn't getting from the animation. I was interested in what was going on, but the music was just irritating and generic to me, in an "I GET IT" sort of way. The lengthy zooms were distracting and boring and didn't help build my interest at all. A quick cut to the words that were being zoomed in on would've been simpler and more effective. The graphics were okay, but even with limited time it didn't seem like enough effort was put into the chat site. Green on black with the universal "It's a computer" font? Meh, not believable and overused. A couple small annoyances were the use of Skype sounds (I had to check to make sure there wasn't actually someone chatting with me and I missed a moment the first time I watched this) and the fact that the person on the other end seemed to be typing faster than anyone I've ever seen. I mean, I don't want it to take 30 seconds for a new message to appear, but when a huge wall of text appears in a fraction of a second after a message a couple words long, it gets awkward. Was this meant to add to the human/bot confusion? I doubt it. :/
What really got to me was that nothing I wanted to know was revealed. If it was a person (I'll just assume it was), s/he did a terrible job of convincing the main character that s/he was real. And the main character didn't ask any of the most obvious, important questions, like "What is your name?" or "Where are you from?". The person on the other end was asking to be helped, but how could this guy help if he wasn't even told anything of importance? There's no way.
The end felt anticlimactic. There was a human on the other end, who was taken away for unknown reasons by nameless people, or a well-programmed bot that faked it. The main character probably thought about this experience for a day or two and then never really thought about it again. The viewer is left to imagine what didn't happen in the animation, to the point where it feels incomplete. I would've cared more if I'd gotten some information.
As a way of making you think, this was fine. It's a very interesting idea and there are many things that could have happened, and what happened is up to the viewer in the end. But as a short film by itself, it was a mostly uneventful back-and-forth conversation between a random person/computer/half computer half person and another random person that didn't head in the right directions. Maybe I'm just not "getting" it, but it was just sort of boring to me after the abrupt end. I think it would've been better if you'd gone ahead and delayed it, since after reading your replies to certain reviews, you think you could've done better if you spent more time on it. Better to release a great animation later than expected than to release a decent one on the target date.
Just my opinion, take it however you wish.
