I give it 3/10 because it is obvious they have put quite some efford in making this movie. But it felt like going for 3 hours. It is not a slow burner , but it just felt long.
Script and plot are ok. Not overly complex, but there is the efford right there. They tried to make a story out of it. So in that regard it is no worse than some of the bigger budget old sequels. While the story is predictable, they even managed to deliver 1-2 tiny twists, and not cliché ending.
Acting is mediocre, but not terrible. I've seen worse (and i've seen worse in big classics.. yeah i know, i'll get thumbs down for talking bad about the nostalgic movies , whatever). While being mediocre, again they did put some efford. It is not amateur joke level as some of the Amityville movies we have recently lol.
CGI is bad but it's not very often so it doesnt strike you in the face :D
Cinematography is below mediocre, at times even bad.
Overall, it's not the worst movie i've seen, watchable, but barely :D if that was popular movie or bigger budget movie, i'd give it 2/10 or even 1/10 .
