Before watching the movie:
I first heard of this movie when I saw pieces of it on TV. Not enough to get more idea of what it was than a trailer could have told me, but Kelsey Grammer caught my attention. It’s been years, so I’ve forgotten much more than “Kelsey Grammer, submarine, ragtag misfits, wargame”, but this finally rose to the top of my list.
On the other hand, that limits what I can say about my expectations. It’s clearly an underdog submarine comedy, and I’m not sure what else I can expect. What little I’ve heard about it otherwise suggests it’s not very good, but I’d hardly call it infamous.
