Well.....I think it's safe to say he has problems.
As always, meta jokes about Lego are quite enjoyable.
While I simply thought something seemed empty, upon second watch, I discovered that this doesn't seem to have any sound except the guy's voice. While it's a testament to his talent that I didn't really notice my first viewing, a few ambient noises would have helped everything feel more full and complete. Still, the voice actor does a great job carrying the plot, conveying the character, and keeping viewers engaged throughout.
The set, however, feels a bit messy and oddly framed. The split from the white wall on the right to the colors on the left isn't down the middle of the frame, nor far enough over to hit the Rule of Thirds. It's in an awkward and unsettling part of the frame, which, when paired with the psychiatrist's placement on the far edge, and that slight dark gray wall on the far right, makes everything feel off. Sadly, not in a creepy "something's wrong here" way that would compliment the dialog, but in a "this just doesn't look cool" way.
Overall, animation looks nice, but the framing and set look odd. The voice acting is great, but a little bit of background noise would have been nice. Yet, even now it's a good film. Basically, working on a couple small things would catapult your next films into new heights of awesome.
