My kids (9 yr old girl, 11 y/o girl, 13 y/o boy) said it was the best movie they have ever seen. They are not super familiar with Looney Tunes. It isn't uncommon that they would see something and immediately it becomes their favorite movie, but the discussions afterward were different.

I loved it (52 y/o dad). I've been fascinated by it since hearing a few years ago about the tax write off situation.

A bit of extra context: since seeing MacGruber, I want to see anything with Will Forte (I know that's misguided, but I can't help it).
