Straightforward and pretty predictable, but 'The Horse in the Gray Flannel Suit' is still a film I enjoyed watching.
Dean Jones is always fun to watch, that's no different here as he portrays Fred. Diane Baker is also up to scratch as Suzie. Ellen Janov (Helen) and Kurt Russell (Ronnie) make for suitable child actors, while Fred Clark plays the role of Tom well. It's the cast that's most likeable about this film.
Plot-wise it's good, the pacing is solid as is the score. Perhaps the run time could've been slightly shorter, but that's not really a serious criticism of mine to be honest. It's all worth a view.
