Viaje a las estrellas IV - Misión: Salvar la Tierra

I saw the Special Collector's Edition of this(which I understand doesn't have any additional scenes that weren't in the original). Ah, 'the funny one'. There is a theory that after a few heavy or dark episodes in a row, they'd have a fun one. This is the movie version of said lighter one. And yet, it's smart, dramatic and, well, a blast. Again directed by Nimoy, and this also partially penned by him, this is superior to the one before it. This could be absolutely lousy, given the concept, but it's... not. It's marvelous. The humor is genuinely well-done, timing, material, it all works. Most of it is verbal, with a little bit of silly, with none of it being childish or worse. The prerequisites to "getting" it, apart from knowing the series, are simply understanding American culture and slang, specifically that of the period. The plot is good. The situations are resolved in a satisfying manner, albeit certain aspects might benefit from more seriousness. The dialog is excellent, possibly the best of any of these I've seen thus far. The language is pervasive, to a greater extent than earlier(and harsher, as well), though some of it is there for a purpose(namely, hilarity). There is another minor offensive thing in this. If viewers can tolerate or look past them, they're likely to thoroughly enjoy this. This has a moral, but it isn't preachy. I recommend this to fans of Star Trek and/or sci-fi, and will suggest that the second film be watched first(the third is perhaps optional). 8/10
