I didn't take much notice of these films when I was a child and haven't seen them since. Maybe I should rectify that!
Not by going back in time to watch them as a child, if you were wondering.
I need to re-watch these too, but also not involving time travel. This new film is still in the casting stage. I fully expect that as we get nearer to the release date, given the age and availability of the originals, the TV schedule will be filled with Bill and Ted. I didn't see them immediately either, but I was aware of their growing cult status, and they do have a certain charm. I don't think this sequel can ever recreate that, as it was partly a thing of its time, but it is totally bodacious to attempt to do so.
