Let's wait for things to actually happen before we complain. There could always be an exception to the rule. I don't care too much for most of these updates (some are actually quite good for what they are), but at least when they happen, we usually get some DVD release out of it. We wouldn't have Smurf comics published in English for the first time ever if it wasn't for that dumb live action film, nor would we have a DVD release of the superior film, The Smurfs and the Magic Flute.
Peanuts don't really need a movie to be relevant, as they always run the specials and they constantly crank out merchandise. Other things do. It's a sad fact, sure... Popeye's going to get a wave of popularity because Sony is going to have a CGI film based on that (that I'm pretty worried about), but Roger Langridge is writing a series of Popeye comics for IDW that are almost forgeries of the original Thimble Theater. That's a win in my book. Other than that, Popeye was dormant as a franchise for years. We got WB to release the old shorts, that was it.
And I'm pretty sure they know if they screw this film up, they're never going to hear the end of it and the Schulz legacy/estate/whatever will refuse to let any of their characters out like that again. It's not like they're a sign out the characters with reckless abandon estate. Otherwise the TV specials wouldn't be based off of existing strips, and we'd see them in more than MetLife ads.
