"The Reptile" is a competently produced and watchable horror entry from Hammer productions but offers little new to the genre. Once again we have new-comers to a district that harbours a deadly secret, who must deal with hostile locals before getting get sucked into events, while ominous music and the classic 'moors' setting establishes tone. The generic characters don't present much of a challenge to the actors (exceptions being John Laurie, whose Mad Peter manages to avoid the usual town-drunk shtick and Jacqueline Pearce, who is very good as the mysterious girl). Sadly, while the movie effectively builds to a climax, the final scenes are marred by the appearance of the titular creature and its sudden anticlimactic death. A fair amount of suspension of belief is required (especially to the 'basement' of the Franklyn home) and there are some plot-driven inconsistencies (e.g. venom works a lot faster on secondary characters than on primary characters), but otherwise, 'The Reptile' is a pretty good example of mid-sixties British horror (other than the absence of Hammer perennials Cushing and Lee).
