I watched this movie several times as a kid, but it's probably been at least 15 years since I last watched it. The first thing I noticed was the cheesy 1980s/early 1990s music. And the hair!!! LOL! I have to say, however, this movie holds its own over the decade. I still found it very enjoyable as an adult and my daughters both loved it too! After watching it we picked up my daughter a few TMNT action figures for Christmas which she LOVES!
If you have an evening and you're not sure what to do, I recommend a family movie night with the Teenage Mutant Ninja turtles. The series has recently rebooted with two new movies in the last couple of years (2014 and 2016). We'll watch those eventually after we work our way through the originals.
