I've always been a huge Pixar fan. I was definitely hesitant when they announced they were doing Toy Story 4 that it would be purely a cash grab.
It was actually very good. Favorite Toy Story movie, no. But I will say if you have enjoyed the Toy Story movies to date, you will likely enjoy this one as well. It has many of the same elements without being a re-hash. It's very Woody-centric. Other than Buzz, most of the familiar characters don't have a lot of time in the movie.
I wasn't sure how the Forky character would work out, but he turned out much better than anticipated.
Don't go in with super high expectations or anything, but should be enjoyable to watch.
