I had seen all the mainstream movies I had any interest in, and felt like a a movie. I do like Brendan Fraser, so $8.50 (senior rate is great) was transferred to the Regal Fenway, and I attended an early evening show. Again, my favorite disclaimer – I am not the target demographic for this movie.
I must admit the movie was entertaining at times, and there were a few laughs. Although somewhat silly from an adult perspective, this movie is definitely targeted for children. I attended an evening show so only a few children were in attendance, and they seemed to enjoy the movie quite a bit. The time passed quickly, the animal characters were funny, and the animal physical forms / CGI were very well done. The raccoon must have graduated from the animal equivalent of Harvard. 
I alway like Ken Jeong in movies, and his role in Furry Vengeance is quite funny.
If you wish to attend a general audience movie with your children, definitely take them to see Furry Vengeance. I am sure it will not be your favorite movie, but it may be your child’s favorite movie for at least a few weeks.
