There are some musicals that are really good, like Grease, Chitty Chitty Bang Bang, and Sweeney Todd.
In these the music is good, the songs are memorable (yet fitting), and they have a great plot.
Chitty is probably one of my favourites, mostly for nostalgia and a few songs (posh, toot sweets, chitty chitty).
Sweeney Todd is my hands down favourite for it's really fitting and powerful songs, a great theme and atmosphere, a stellar cast and acting, as well as being deliciously morbid. A perfect mix of black comedy and musical.
It also doesn't leave you wishing you'd gone to see the play instead, like Les Mis.
I know relatively few bad musical films, but that's more a product of me not knowing many musicals at all.
I really have to be forced to watch a musical when I know it is one. Otherwise it has to trick me.
Sci-fi is a rather general term and covers a lot of themes. Whether it's space, time travel, clones, AI, or that bullstuff about using more than 10% of your brain (although Limitless was good). I'm very glad the poll seperates Sci-fi from Fantasy, as the two are often merged, despite often having contradictory themes, and putting them together makes them more useless as descriptions.
There are some really great sci-fi films, like Star Wars/Trek, Hollow Man (also a thriller/horror), or I Robot.
And there are awful ones, like The Last Sentinel, or Lost in Space.
I think often budget is a limit to good sci-fi, as in the case of The Last Sentinel. But sci-fi brings an unexpected pleasure to that at times. Cheap budget films like Sharknado, Megashark vs Giant Octopus, or (my favourite name) Airplane vs Volcano.
They're admittedly comedies, where the cheap quality is some sort of anti-joke that never ends.
Still, they are often crammed with awful fake-science, and such quasi-comedies wouldn't work with most other genres (Horror/Zombies being an exception; see my earlier post that mentions Dead Snow).
And I do love these films for being so bad.
I don't particularly think either genre is a great term, for being quite vague.
But on the whole, there are fewer musicals that I love, than there are sci-fi's I love.
And sci-fi manages to entertain me when it's great, and when it's truly bad.
So this time I choose sci-fi.
