So, therefore, hence consequently

[Ryan.]

Can "hence", "therefore" and "consequently" be used instead of "so" in the sentence below? If so, please tell me about the correct use of punctuations in them.

A-"I found this movie charming so I decided to watch it again."

1-"I found this movie charming therefore, I decided to watch it again."
2-"I found this movie charming hence, I decided to watch it again."
3-"I found this movie charming consequently I decided to watch it again."

Thanks a lot.

The other three require a period after "charming" and a new sentence. (A semi-colon would work.)

"Hence" is a bit pretentious for this use.
"So" is much more natural than either "therefore" or "consequently" in this use.
