Spy Kids 4 and Slightly-Related Book Series

Maybe you've all heard -- maybe you haven't -- maybe I'm the only one who cares.

    But there's going to be a Spy Kids 4.

    Okay, I love those movies.  Always have.  I was probably in kindergarten or first grade when the first one came out, and everything about it -- the gadgets, the missions, the fact that the kids were spies -- fascinated me. 

    Also, the thumb-people and the guy with too many heads really freaked me out. 

    I really don't know about this fourth movie, though.  Carmen and Juni are adults now, and according to a Yahoo! article (which is how I found out about the movie in the first place), they're "still with the OSS and give the new kids -- Rebecca (Rowan Blanchard) and Cecil (Mason Cook) -- some pointers and much needed spy gadgets in their battle against the fiendish Timekeeper".

    All this kind of reminds me of what they do in books sometimes -- finish a series, then start a new, slightly related one, usually with an original character's kid as the new main character.  I hate it when they do that, so I figure I won't like this movie, if I even convince myself to watch it. 

    So really, in a small way, this has to do with writing.  Granted, the connection is pretty slim.  And sort of tacked onto the end, almost like an afterthought. 

    But mostly, it wasn't.
