The Last Kingdom: Seven Kings Must Die

A nicely done extention of the series but it did nothing to move the Uhtred story forward.

I realize the final battle historically actually occurred and the participants shown were there (except the fictional ones of course) but was the entire movie necessary.

I feel it was not.

I liked the ending of the series and was happy to imagine what may have happened after it ended.

The Last Kingdom was a fantastic series from Bernard Cornwell's exhaustively researched books and I was happy to rewatch the entire series from start every time a new season was released.

Could you miss seeing this film and still feel the series ended well?

Yes, absolutely.
