I most recently watched the uncut version of the 1986 live-action movie adaptation of Howard the Duck. Yes, that one, the first Marvel movie ever, with the bad reputation for being a flop that almost ended George Lucas' career.
I watched the original PG-rated UK release as a youngster and, though it was a little bit disjointed, I found it good fun - enough to pick up the tie-in computer game for the Commodore 64 (which is less fun - it feels like its team weren't given enough time to flesh it out), which I also revisited a few weeks ago. I recently picked up the uncut version of the movie on DVD (which carries a 12 rating in the UK), and found it even better - the restored footage allows the whole movie to flow properly for the first time, and it's just as fun as it ever was.
The script is quick and funny, and if you blink you'll miss several jokes and references at any given moment. And there are a lot of duck puns, too. There's even a hilarious point where the villain - a demon from outer-space that has possessed the body of one of the side-characters and is gradually transforming him into a monster - briefly abandons his grimdark monologuing (which, amusingly, nobody is listening to anyway) about how the world will see all-encompassing doom and neverending hell on Earth, simply to make a sarcastic and mildly-irate grumpy-old-man one-liner about the main characters, before going back to what he was doing before. It's humour that most people didn't get back in 1986, but which is hilarious to absurdist sensibilities in 2021 (at least it is to mine, anyway
).
George Lucas always held that the movie was just released in the wrong decade and that it would be appreciated better in the future, and I have to say that he's right. The film clearly never takes itself seriously for a moment, so I'm not sure how anyone watching it ever tried to do so back in the day!
I suspect that, were it released with minimal alterations tomorrow as a new MCU movie, without the baggage of its 1980s reputation, it would probably be a big hit with the crowd that enjoys the irreverent comedy of Guardians of the Galaxy (whose movies happen to aim for a similar sort of soundtrack and vibe to this one) and Deadpool - characters that, not surprisingly, Howard has been published alongside in the comics. If you're old enough and don't mind the look of the animatronics (I personally think that they're well-done for the era, especially considering how little pre-production time the movie was given), give it a watch - it's actually better than people say it is, there's almost nothing in there to show its age (one scene features a pager beeping and its owner saying that they need to take a call, but you never see the device - modern viewers would just interpret it as someone receiving a text-message on a mobile-phone), and you don't need any knowledge of the comics to enjoy it for what it is, since it's kind of a standalone thing.
