A: Worst Bob Hope comedy ever(and that includes some heavy competition). Hope, on an island with sailors, dreams aloud of being in a bathtub with a geisha girl "steering his ship". Somebody certainly steered this Hope-hackery over the cliff, as it features Phyllis Diller and Gina Lollobrigida and still can't work up any laughs or excitement. Where's Bing Crosby when you really need him?

A: This two-parter was excellent - the best since the series returned. Sure bits of the story were pinched from previous films, but what TV shows don't do that these days. What we got here was a cracking good sci-fi story. A great big (really scary) monster imprisoned at the base of a deep pit, some superb aliens in The Ood - the best "new" aliens the revived series has come up with, a set of basically sympathetic and believable human characters (complete with a couple of unnamed "expendable" security people in true Star Trek fashion), some large-scale philosophical themes (love, loyalty, faith, etc.), and some top-drawer special effects.

I loved every minute of this.

A:
How cynical are the writers, to pander so. I may be an American citizen, but I don't need to see other Americans pat each other on the back for an hour and half in order to enjoy a film. I'm astonished that so few have commented on how utterly jingoistic, sentimental and trite the dialogue in this film really is. The historical inaccuracies of the film are not as gross and offensive as in "U-571" (which changes British submariners to American ones) but you still walk away feeling a little slimy. Really, the Germans in this film do nothing but admire the Americans between battle scenes! How sad, unnecessary! I'd just like to say to the writers: it's obvious to many of us that you can't capture real people, with real problems, under real pressure, and that you've taken some very well tested shortcuts. Lucky for you there will always be nationalist nutjobs to appreciate your sugar-coated tripe.
