Owen Hughes’s review published on Letterboxd :
Hmmm. I've seen some poor reviews of this film, but I didn't think it was all that bad to be honest.
The most impressive thing about it is, like the first film, the creativity that goes into dreaming up the special effects/make-up. Some of the more imaginative effects are the only things that makes the film a bit creepy, although the original has the edge on it in that respect.
Aside from that, the film is pretty terrible. The situations just aren't scary enough and are just very silly (being tied up naked in the showers and whipped with a towel?! Parrakeet's scratching your face?? Really?), the characters pretty bland/uninteresting, and the deaths just boring. There's no horror! It's all very camp and stupid.
Some of it is just so bad it's good, but it's not the worst film ever made.
