Frozen Scream (1975) 
Frank Roach's Frozen Scream feels like the bastard child of many a horror film, in as much as you not only get the impression of it feeling a little cobbled together from various independently sourced ideas, but also the recurring feeling that you've seen a lot of this before somewhere... most of it having been executed a lot better too.
However, it's hard to completely dislike a film revolving around mad scientists kidnapping and experimenting on the general public with a goal to turn them all into 'frozen' immortal zombies… and whilst there are certainly a few interesting scenes dotted throughout, Frozen Scream doesn't quite live up to its premise unfortunately.
The main let down here is the lack of a decent, and above all engrossing script, resulting in a haphazard, plodding pace; itself glacial at times - which is strangely fitting when considering the film's title. The performances are also excruciatingly painful all around and the dialogue does little to help, although neither does the abundance of stilted and monotone delivery of the lines from the cast - and we're not talking about the zombies here either. The frequent narration (which is mainly used as a device to build bland backstory) even talks over the on-screen dialogue at times to the extent that it leaves you wondering whether the audio syncing has been done correctly post production, or whether this was intentional. Neither would surprise me.
Overall, what could have been a chilling, suspenseful little film feels like a missed opportunity riddled with poor pacing and incoherent plotting issues and certainly won't be something I'll be returning to anytime soon.
