I really quite enjoy the Star Trek movies, especially the most recent 'reboot/prequal' ones with Chris Pine playing William Shatner playing Captain Kirk. Great fun!
LOTR? Not for me, sorry. I fell asleep about 20 minutes into the first one, and never woke up to any more.
Here's a small variation on a theme, which may or may not appeal. What about three different movies of the same film? I did this during Lockdown with an old favourite, 'Goodbye, Mr Chips' and thoroughly enjoyed all three versions that I found. Timewise, they're well spaced out, and although the plot is essentially the same, there are three very different treatments: The original black & white movie with Robert Donat as 'Chips' (he won the best actor Oscar for his performance) and Greer Garson; the musical version in 1969 with Peter O'Toole and Petula Clark; and the 2002 TV series starring Martin Clunes and Victoria Hamilton, and which has been stitched together to make one film-length version available on YouTube. I enjoyed all three very much, and I won't say which was my favourite in case anyone wants to watch and we can compare notes afterwards. And it will only cost you 6 hours and 50 minutes of your viewing time.
PS... Whilst checking the exact details of the above, I discovered a 7-part TV series of the same story filmed in 1984 with Roy Marsden and Jill Meager, all episodes available on YouTube. Deep Joy - that's my treat for today!
And if anyone's thinking "why watch the same story three (four) times", my answer to that would be "how many times have you seen 'The Great Escape' or 'It's A Wonderful Life' or 'Love Actually' at Christmas? At least those I've mentioned above are three different films. And I'm the guy who's seen 'Apollo 13' at least 13 times now... still affects me every time.
