Granted, it's not the best Bond movie so far, not even the second best. But I like this more than OHMSS. And not because Connery was back. No, that probably wasn't the best idea but one born out of desperation. His age (althought just around 40 he looked older) is clearly showing by now and he isn't as convincing as he was before. I do agree that there is a lot of sillyness in this movie. But in some way that's what I expect from a Bond movie. Not a parody but certainly a wee bit over the top. But it seems to be more aimed at an american audience. The addition of well known, and beautiful, american actress Jill St. John seems to add to that.
[spoiler] There is no mentioning at all of what happened at the end of OHMSS and I think that was a deliberate attempt to bury that movie. We start out again with Bond chasing Blofeld (again played by a different actor) around the world and presumably killing him. Which is later revealed to be a Doppelgänger. Not a huge surprise for the audience I might add. The two henchman Wint and Kidd add a little bit of creepyness and overall you get the usual plot holes and errors also typical for a Bond movie.

But it was "Goodbye" for Mr. Connery who carried a lot of the 1960s Bond with him. The next one would by the premiere for Roger Moore (who was the initial first choice for the character) who carries Bond into the 1970s.
