On the outbound flight I sat through:
American Pie: The Reunion - not the funniest of the series, but some great moments and the intro tickling me no end (so just what the other passengers thought of me...!). Stiflers 'big laugh' (there's one in each movie) was the only letdown
Karate Kid (original) - missed the last 10-mins as the system shut down before coming in to land
Prometheus - interesting. Holes galore, major questions throughout left unanswered, disjointed storytelling; but, whoa!, neat twist at the end which I did not expect (I haven't read any of the blurb about this film, I just needed somethin to occupy me during the flight, so I was spoiler-free)
MIB3 - better than the reviews I've seen
And on the inbound flight:
A Knight's Tale - great movie, decent humour throughout (though I found the early scene involving the dead jouster tickled me throughout the whole film. I've even now just had a giggle thinking about it!)
Goldfinger - why did I with so much choice. I'd planned on watching several movies on the way home and thought I could fit this one in early, but found myself re-listening to my CD Jukebox choices too often. Bah! Not a bad movie, just soooooooooooo predictable after all these years and repeated viewings on tv.
And tonight I will be watching the BBCfour evening of Beach Boys documentaries.
