It's not just this movie release, ALL the movies have been around $20 to rent when they first come out since the pandemic hit. It's ridiculous! People complain about movie ticket prices, but the $20 fee is only worth it if you have a family and you're all going to watch the movie.
The $20 dollar fee is also worth it if you're going to watch the movie more than once. Kids especially are happy to watch the same movie over and over, so if you get one they like, then you can really get your money's worth. Although, at that point, it would probably just be best to buy the movie!
