Dated Movies after 1970?

[Jezza]

I thought this would be an interesting subject to bring up since members from time to time on this forum do refer to some movies as being dated and I thought it'd be great to see what movies people here thought are a bit dated.

As you can tell by the title you can't choose films prior to 1970, I decided to do this since there are arguably a number of movies before then that could be classed as 'dated' very easily, especially with the likes of the 1950s B-Movies, and I thought if there wasn't a date in the title then the thread could become overrun with 1950s sci-fi B-Movies, and that would be a bit repetitive.
I also came to the conclusion that it was roughly in the 1970s where the modern-day Hollywood blockbusters were established, and I was curious to see which of these sorts of movies people here thought aren't quite as impressive as they were when they originally came out.

So, which movies after 1970 do you think are dated by todays standards?
