The scar is rather pointless if this is the only film he appears in.
I would say, for all that has been made of this film; the 'return' of the 'archenemy'; the casting decisions - purposely using an actor whose recent work includes reinventing the archenemy of another iconic character - the Oberhauser setup; the brilliant Waltz; the reinvention of Spectre; for all of this boo hay Blofeld has been barely scratched on the surface. If this really should have been 'it' then they wasted the opportunity.
No, Blofeld must return.
Quite. To me this film feels like a setup for the next ones (which is also why I don't think Bond retired).
Unless of course Tracy, I mean Madeleine, is shot through the window of a car as they go off to start a life together. I was really expecting it at the very end of the movie and won't be shocked if we see it at the start of the next one. My only hope being that both Waltz and Seydoux return if they go that route. I certainly hope the producers signed both of them with an option for a second film. The film certainly wraps things up if they do not return to this story line, but it also leaves the door open enough if they want to continue the storyline. It does not even have to be an elaborate escape - just that one of C's men took Blofeld into custody and then set him free. Things are certainly set up for a wheel chair to make an appearance.
We were on similar wave-lengths here, Pushkin. I thought the same of the ending of this film and the possible beginning of the next one.
As far as Blofeld escaping is concerned, perhaps it'd be all too easy. What, with MI=6 still setting up shop and finding some permanent digs with well-equipped holding cells. After all, the underground facility has seemed to be disused as of the events of SPECTRE and White Hall has only been shown as an office building, more or less. Besides, with how many crooked agents pop up here and there, you'd think they grew on trees. It's no wonder M became so fond of 007... He's one of the only one's who has stayed completely loyal!
I'd like to see something similar to the PTS of License to Kill happen. Sparing details, as Blofeld is being transported, the armored truck plunges into a body of water and he makes a narrow escape underwater with help from his organization.
