Reviews have to be balanced to circumstance. There is a big difference between putting out the sales brochure and the notice on the bulletin board. Likewise in coding a cryptographic framework for general consumption and that little script to create personal slideshows based on how you've tagged your photos.

As a general rule, wider distributions, public distributions, and long-lived distributions need more ambitious reviews. If the distribution is wide, public, and permanent, then everything needs very detailed scrutiny.

I have found some success in starting with and occasionally revisiting review goals. This helps create and maintain some consistency in a process that is scaled to the task at hand.
