When you "buy" a movie on Amazon or Apple, you are leasing a license. If rights change, your purchase disappears. A Blu-ray sits on your shelf forever. For a franchise like Sonic , which has a passionate, long-term fanbase, physical ownership is an insurance policy.
A lively family-friendly blockbuster with a solid Blu-ray package — recommended if you enjoyed the movie or you collect modern family action-comedies.
