I love how casual they approach time travel. It makes no sense, is incredibly inconsistent, and the more you think about it the more you’ll hate it. But it’s a fun series everyone must watch.

Spoilers:

The time travel mechanic literally makes Bill and Ted the only people that matter, ever, in the history of time. The world belongs to Bill and Ted and this is their playground. I love how the characters recognize this in the movies too, so the writers obviously knew their time travel dynamic was goofy.

At least in the first movie:

• Only people who can change their future actions that’ll have an impact on the future is Bill and Ted (time traveller who told them to pass a class influenced Bill and Ted to change their future actions)

• If someone other than Bill and Ted interacts with a different time, it has effectively zero impact on their future actions and society is largely unchanged (ie stealing Socrates and Napoleon into the present didn’t really affect modern society, and nobody found it weird a blue phone booth existed in the 1700s?!)

• Even though Bill and Ted are time traveling, any time they spend time traveling counts against an absolute timeline leading up to their presentation.

I think some of these dynamics changed in the second movie, and again in different ways in the third movie but don’t remember it’s plot enough to defend that claim.

Which one? Year? or you liked all?

Oh yeah, I watched it so many times.

If I can't choose Bill & Ted then I'd say Terminator 2.
