Supergirl: The Complete Fourth Season might on the heavy-handed side in its dealings with current events, but even so the performances for the most part have been respectable especially from Melissa Benoist who embodies the role so well.
Supergirl might not be some misunderstood movies of the 1980s and indeed it is at times pretty awful, particularly in terms of the cheap production design, bad dialogue and nonsensical moments, and yet the movie has its charms, most notably Helen Slater.
The 80s Overdrive: 6 Movie Collection is just another re-package job by Mill Creek, a few triple dipping at this point. I guess if you didn’t already own any of these movies, and considering its low SRP, might be worth picking up, otherwise skip.
