As with all of Troma's movies, this is definitely something of an acquired taste. There has been some fun enough titles amongst the movies produced by Troma, but far from all are equally great.
While there were fun moments, and your standard outrageous Troma moments to be had here in "Return to Nuke Em High Volume 1", then the movie tended to drag out for long periods of time, and it just ended up as too much towards the end. There was so much nonsense in this movie - but hey, it's Troma!
Effects-wise, well if you are familiar with any of the previous Troma movies, then you know exactly what you are getting into here. For those who are not familiar with Troma's work, just a little heads up; lots of cheesy, low budget, outrageous and wacky effects, creatures, and spoofs throughout the entire movie.
There were lots of strange, funny, outrageous and just downright odd characters in "Return to Nuke Em High Volume 1", as in all of Troma's movies, so no big surprise there.
What ticked me off in this movie, was the lack of an overly coherent and appealing storyline. Without proper contents in a story, then all of Troma's oddball effects just wears thin.
