I haven't seen this yet, but I get what you are saying. To me the last couple Bond movies have been very "dark", much more so than the older Bond films. I agree that they should go back towards the silly cartoonish antics.
I'm really not torn either way. My personal preference is for the old style, they were entertaining for the fact that you didn't have to take them too seriously. The new direction is also fine, but it just seems like they are relying on the 007 name, but not really taking into account that they are being judged on a different level now than they used to be.
I do get it, if you are going to be a darker, more "real" type of film, the classic tour through the test facilities doesn't really fit. It's almost like they are kind of writing the same *******, took out the humor, gadgets and cool cars and replaced that with dead air. I don't find Spectre to be a terrible movie, it's just kind of out there and falling into a genre where other people are doing it better.
If that makes any sense.
