Just returned from the movie theater where I watched BEYOND THE SEA.
Here is my opinion.
The good: The musical numbers, some of which were just like out of a Gene Kelly film! Kevin Spacey is a wonderful singer, and not a bad dancer. The costumes were great as were the sets...they did a fabulous job of capturing the various decades.
The bad: The constant foul language, which seemed most unnecessary. John Goodman (who just seemed out of place in this film).
All and all I was entertained, but probably would not watch the whole movie again...however, I would consider getting the DVD someday just to watch the musical numbers.
