This wasn't necessarily the worst movie but it was certainly nothing special with mediocre acting, the most basic filming and that overall below standard no substance thriller feeling. No build up, no intrigue. While I was somewhat impressed by the practical effects and puppetry of the ray like aliens themselves, the end set design was laughable, the cardboard characters and obligatory romance were hollow, and the lack of suspense or cleverness in any of its reveals and everything else left this project lacklustre, feeling like a shell of an Invasion of the Bodysnatchers type plot (though The Puppet Masters book technically predates the Bodysnatchers book, the latter's adaptation(s) was/were definitely given much more thought). So my recommendation would be to watch that instead (and close your eyes at the weird dog scene).
