The 1990 follow up to the 1989 "Killer Crocodile" movie wasn't really a step in the right direction. Not unless you count a cheesier and campier storyline as better, or having an even more inanimate crocodile as being better.
The storyline in "Killer Crocodile 2" was a direct continuation of the events and story in the 1989 movie, for better or worse. But then it gets weird, because apparently one crocodile survived from part I and it emerged from the egg as a hatchling. But wait, within mere minutes apparently, it had grown bigger than the crocodile in the first movie. There was no time lapse to the storyline, which was a total slap in the face of the audience that have sat through the 1989 "Killer Crocodile" movie.
The events were less interesting in this sequel, and there were far less deaths throughout the movie in comparison to the first movie. And that was something that made the movie suffer.
As for the acting in "Killer Crocodile 2", well it was equal to the level of acting in the 1989 "Killer Crocodile" movie, so you know what you are or aren't getting here, depending on how you look at it.
I found this 1990 sequel to be less adequate in terms of entertainment and enjoyment in comparison to the predecessor. I managed to get through the movie, but it was an uphill battle because the storyline was essentially pointless and non-existing.
