Example: He complains about sound in space, yet does not complain about outer space dogfighting. If you're going to complain about one impossible trope, why not complain about them all? Answer: he is full of shit.
No. Answer: Tropes are not (generally) a bad thing.
He does not critizise sound in space like it is used in almost all sci-fi - that "loudest spacefighters I ever heard" in the beginning is obviously a joke to be taken lightly, not a serious complaint - but he only critizises when it goes too far: that "u-boat" scene on the Tigerclaw. Okay, you can argue that they do not in fact worry about being heard, but surely you can agree it is easy to get that impression and they should've taken more care in avoiding this impression in the scene...
Yes, almost all Science-Fiction uses "sound in space" - but only to the viewers benefit. It is implied that in-universe, there is no sound in space - or alternatively the sound they hear is generated by their own computer from sensor data, similar to how one WC game manual explains it if I'm not mistaken.
The gravity thing: I'm aware of no Science-Fiction that does that at all. Or let's clarify, Post-"2001: A Space Odyssey" non-comedic Science-Fiction.
Why not complain about the Old School Dogfighting AT ALL? Well, because that's the whole premise of Wing Commander. Without it, there would be no movie. Or games.
I think, Spoonys reviews like this may actually serve a useful purpose. Think of the younger ones. The current generation of gamers and espcially those yet to come don't know Wing Commander at all. Also I've experienced people who had seen the movie, but didn't know it was based on a game series at all. A video like this one can help these people to check out Wing Commander again, and so learn an important part of videogame history - which is notoriously underrated in the broad public if you think about it. Lots of people who grew up with consoles, didn't even think about what the PC might have to offer.
