I enjoyed getting to see them again even if they have not really aged that well. In particular, there were several comments made in both movies that bothered me due their sexist and homophobic natures. Still, they were a product of their time, and both movies still stand out due to their unique humor.
Of the two, Connor and Rowen liked Bill & Ted's the best while Dundee edged into Trevor's favor since it was not quite as ridiculous. For me, from the opening song from Bill & Ted's (I have subsequently not been able to figure out how to purchase it), I was surprised at how much of the movie and its humor still holds up. Also, I was again surprised by a movie showing a positive view towards a teacher (even if he is warning them that they will flunk if they don't do a great presentation). Meanwhile, Dundee still works as an advertisement for people to visit Australia. The boys were certainly interested in going there after watching.
