We’ve written about this before, but it seems time for a reminder since school is almost over, and we’re all going to be hunting for summer activities before too long. If it’s movies that will fill your time with kids, don’t forget to check out the ratings — plus these three sites, which offer really detailed dirt on what you can expect from even the safest-seeming flicks.

• kids-in-mind.com – awesome details here.
• parentpreviews.com — this site gives out grades.
• commonsensemedia.org — here, movies get “On,” “Off” or “Iffy” ratings.
