Watched the trailer with the sound off and clicked through it a bit so I didn't see everything.

First impressions are that it looks a bit over the top.

must admit i didn't think U-boats made the habit of surfacing and going into drive-bys w/ their intended targets :-/

They technically "sank" more ships by gunfire than by torps as they often used a torp to hit a ship which, if it didn't sink immediately, was then left behind by the convoy as it slowed to a stop and it was then finished off by the surfaced U-Boat hours later using the deck gun.

Additionally, as torps were very limited but deck gun shells were plentiful, a lone ship wouldn't be torped but hit with the deck gun instead, leading to the invention of allied Q-Ships, which looked like a normal unarmed ship but was actually heavily gunned and designed to engage the surfaced U-Boat thinking it was about to get a easy kill.

I might be wrong but in passing I seem to recall hearing that a lot of the U-boats weren't like proper submarines - for any real speed travel or combat they had to operate on the surface or partially sub-merged - they'd only dive to try and stay undetected.

More or less true: a U-boat could do about 17 knots on the surface, but a maximum of about 4 knots submerged. And that would flatten the batteries pretty quickly. Convoys were usually about 8 knots, and "Fast" convoys about 12 knots. The U-boats would try and get in front of the convoy, then submerge, hoping the convoy would sail overhead. Then they would go to periscope depth and try and hit a ship or two. The escorts would aim to force them deeper and stop an attack, knowing that they would almost certainly never catch up again. This is up to about 1942. After that the there were enough escorts to make it worthwhile for them to attempt sinkings - a process which could take hours.

And Tom Hanks is way too old.
