FWIW, here's a simplified version of my ~/.perlcriticrc:

severity = 3
verbose = 9
[RegularExpressions::RequireExtendedFormatting]
severity = 2
[Variables::ProhibitReusedNames]
severity = 5
[download]

For modules I like to increase the severity of ErrorHandling::RequireCarping to 4, and sometimes I need to reduce the severity of Modules::ProhibitExcessMainComplexity down to 2.

I've found this gives a decent balance between reminding me of best practices vs. annoying nitpickyness. I do make use of "## no critic (...)" as necessary.
