I didn't realize this movie was new. I loved Chicken Run as a kid, and assumed I just missed the sequel before it was added to Netflix. As a result, I had no preconceptions going in. I liked it!
It felt like a blast from the past, and I love the charm of the claymation. The stakes were a bit silly, but I enjoyed the callbacks to the first movie. I also feel that it was super believable that Ms. Tweedy would immediately remarry for money and power given her personality. I'm in my 30's and I enjoyed it.
Overall, a fun thing to watch a slow night.
