As others have said, this movie is definitely weird. If you’re in the right mood, that’s great. Otherwise you might just find it ridiculous and unrealistic.

Although I can’t deny that “Forbidden Planet” is a superior film when it comes to acting, set design, visual effects, a more consistent tone & clearer message – I think I kinda enjoyed it’s low-budget follow-up, “The Invisible Boy”…more. For one thing, I prefer this brand of humour – the spoofing of 50’s sitcom families, the parents’ deadpan reaction/nonchalant acceptance of amazing events such as their son’s invisibility, etc – much funnier than the booze-seeking shenanigans of the Cook, whose eye-rollingly lame scenes pass for comedy relief on “Forbidden Planet”.

The bizarre shifts in tone and plot absurdities/illogic in “The Invisible Boy”, can be seen as weaknesses, but at least they make the movie less predictable. One can argue that “Forbidden Planet”‘s script ties everything up *too* neatly, that there is too much foreshadowing, and the clues a bit too obvious, as to the origin of the monster. I figured out what was going on there, long before the climax (and I didn’t need a brain-boost!) “The Invisible Boy” had more surprises.

Another point in this film’s favour – Robby The Robot gets to show more personality, express a wider range of emotions (I’m not kidding!), and is even more lovable than in the first film. It probably helps that Robby didn’t have to compete with any great actors like Walter Pidgeon here. But I do think he has more screen time and more opportunities to shine in “The Invisible Boy”. He tugs on the ol’ heartstrings and really steals the show.
