A guilty pleasure for me personally, as I love both 'The Great Escape' and most of the works I have seen, over the years, from this rightfully-esteemed British animation company. Highly recommended both for children and for adults who enjoy animation.
Made my roommate who hates stop-motion animation watched this in 2018 and even he had a good time. It's maybe not as great as I remember thinking it was when I was a little kid, but it still holds up to some degree.
_Final rating:★★★ - I liked it. Would personally recommend you give it a go._
