"Puppet Master 5" is technically superior to its predecessor, moving from 'hilariously terrible' to...just 'terrible'...Damn it! I can't even laugh at the badness anymore. Instead I just have to be bored.
"Puppet Master 4" seems cheaper than previous entries of the franchise, which is strange because it boasts such a high profile concept (killer puppets vs demons). But it's also just a bad movie that finds any semblance of redemption by providing lots of unintentional hilarity. Plus, at least it's very short.
"Puppet Master 2" is not exceptional horror and carries its own bag of flaws, but at least it was 'sometimes' entertaining and delivered more of what I expected from the previous one.
