These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: Aside from fan reaction to the TV series in general (explained via the Flanderization trope on the main page), fan opinion on both the films is quite mixed. Is Tenchi Muyo! in Love a finely-written, well-paced action film with more of the OVA's charm inserted into it, or is it a boring retread of Back to the Future? Is Tenchi Forever! a subdued, dramatic masterpiece work in the Tenchi Muyo franchise, or is it too different in tone from the previous Tenchi fiction to the point where it loses what made the original memorable? And within Tenchi Forever!, are the revamped, more realistic character designs justified in that they fit the tone of the story better than the previous, stylized ones, or were the original character designs fine as-is and the redesigns are an unwarranted change? To say that debates cause headaches within the fandom to this very day would be a gross understatement. And that is all that we will say on that matter.
