This felt urgent and yet kind of laid back... cinematography is great. There were times when I didn’t know whether to laugh or take my breath... as mentioned by many the final sequence chills, angers and upsets.
As often seems the case it's the direction and pacing that rather lets down the dazzling Harryhausen monsters in this early foray for the legendary animator. However, in view of the very small budget, the final 20 minutes are terrific: "IT" comes up for air (via the Golden Gate bridge) and lets rip...
It's got some nice '50s zingers, a rather off-beat love triangle (?) and looks good in the "colorized" version that I watched. A sweet note on the film from Joe Dante is one of the many extras (many others of which I'm yet to get to) in the Indicator box set.
