Y'all take a gander at this segment I took out of a review on IMDb, will you? I can tell from the context what ooky and midquel mean, I think, but have any of you heard these terms before?
This midquel is squarely aimed at the lunchbox-tetherball set to the point that unless you're a complete animation nut like yours truly, you might find one or two scenes a bit too cloyingly ooky to your liking.
It is what I would normally consider a sequel...okay, it's Bambi II--I wanted to see if that was indeed Patrick Stewart's voice I thought I'd heard in the previews; as far as I know there is no movie that follows it. That would be hard to do, in fact, as this movie was just made.

ooky, a. colloq.
[Prob. alteration of UCKY a. Cf. earlier ICKY a. and slightly later OOK n.]
Unpleasant, repellent; slimy. Chiefly in extended use: sickly, sentimental. Also: peculiar; unsettling. Cf. ICKY a.

1964 S. BELLOW Herzog (1965) 277 He writes poems and reads them to Mama... He looks ooky when he says them.

ooky I'm familiar with, though I'm not sure I have ever seen it written, but midquel, no.

I would think that midquel implied another movie to follow, whether there was one that was actually in any stage of production or not. One might consider the various post-Stone Harry Potter movies.

I would have thought its origin betrays the sense being reached for, but not entirely clearly. Sequel was obvious in meaning, and led to the coinage prequel to describe a story set before the tale that was first told – eg, the 3 Star Bores ‘prequels’. Surely therefore midquel is suggesting a segment that inserts into the middle of an existing storyline?

Geesh! Word's not even dry behind the ears and already you're prescripting about its misuse.

ain't often I gets torn off a strip fer that!

perhaps it's more a midscript?

The Disney movie Bambi is based on the book Bambi: A Life in the Woods by Felix Salten. He wrote other books in the series including Bambi's Children: The Story of a Forest Family which I would assume takes place quite a bit after this new Bambi II.

It seems that Felix Salten may have also written a famous bit of erotica, an autobiography of Josefine Mutzenbacher. Reminds me of Roald Dahl's varied output.

I'm a big fan of Dahl's but I didn't know he wrote any erotica.

You might want to read these few paragraphs. I remember reading some of Dahl's short stories in Playboy.
