Finally got around to seeing this and boy what fun movie AH was. The acting was excellent all around , but more importantly I thought the movie was fun and it held my interest from start to finish. American Hustle could have had a 4 hour run time, and I would have happily sat there and watched all 4 hours.
American Hustle and Silver Lining's Playbook have really made me a fan of David O' Russell and I look forward to seeing what he does next.
