The main problem is the bad script and dialogs and the pretentious style which tries to keep the tradition of older Bond films incorporating some not-so-witty and cliché humor and ludicrous action sequences with nothing new to offer. Planes, helicopters, cars.Well we’ve seen it all before and in much better executions.
Also Blofeld( or should I say BLOWfeld), despite the fact he is the King of all previous villains, seems quite harmless.
Casino Royale( 2006) is far more entertaining( I’ve watched it again recently) and engaging. Spectre is Meh! in almost every department including( unfortunately) the ladies.
