Frankenweenie is a gorgeous looking film. If you are going to see it, see it in 3-D.
(Keep in mind here that I am of the firm opinion that before Frankenweenie there were exactly 6 films worth seeing in 3-D.)
The reason that you may not want to see the film is that like The Wizard of Oz's Tin Man it has a ticking clock where it's heart should be. Originality and character development are sacrificed on the altar of continuous homages.
It's entirely possible that the reason that I disliked the film is that I have seen too many of the films that Tim Burton likes, (or that I'm crazy) so it might be great for kids - who presumably haven't seen all the Universal Monster Movies (and the Godzilla series and the Gamera series and Willard/Ben and etc...)
In terms of the 3D, for animated films only Coraline tops it.
The other 5 on my list of worth paying to see in 3D in no particular order are: Cameron's Avatar Scorcese's Hugo Scott's Prometheus Herzog's Cave of Forgotten Dreams Wender's Pina
Is it just me, or is it basically "Nothin' But a Good Time" by Poison? I was suprised at how "bippity-bop" the song was for these guys. But Dilana did just right with it -- sell it for what it is, & don't try to overwork it.
