Is there a more rewarding way of spending 90 minutes than watching Lynch putter, reminisce, and work on a sculpture? Maybe, but you'd need to give Lynch the budget to produce another feature to find out.

For some viewers, it will be more than they want to know, but for Lynch's many partisans, it's required watching.

No one else weighs in on Lynch here - it's all him, all the time. And, although chatty, he's not the warmest or most engaging presence. Still, Lynch devotees should dig this respectful, offbeat portrait.
