Before I point out flaws, I preface thusly: Billy Bob Thornton is the greatest non-Johnny Depp actor working in Hollywood films today. Somebody cast him in something halfway intelligent opposite Jack Nicholson and we can all call it a day. Now, “Bad Santa” is one of those troublesome movies that has a lot of fantastic things going for it and just as many problems. I laughed my arse off when I was supposed to, but at other times I kept wishing I was home so I could hit pause and go check my email. It is a flawed, flawed movie that has some timeless bits we’ll be laughing at forever. Tony Cox ought to get the Oscar for supporting.
