A fitting conclusion to this wonderful series!
Not only have you retained the usual charm and innocence, but this installment certainly impressed with the great special effects. The hamster effects in particular were well rendered, and utterly hilarious. The zoom transition at :30 was a nice touch, and I'm impressed with how well the two shots lined up.

Was this the first time we've seen subtitles from Barney? Perhaps my only real critique was that they simply were not necessary. Sure, it made the joke more clear, and including them makes sense, however, the joke probably could have remained simpler without them. Yet, that's only a tiny nitpick, and the rest of the film is still spectacular.
