There's plenty of things in films that are meant to be real but aren't though - I'm not going to go watch X2 to point some out from that film, but things like people jumping through plate glass windows, sounds in space, bullet time reactions, cars blowing up on impact when they fall down a canyon, people being "blown away" by shotguns, visible laser beams.... there's hundreds of basic things that are wrong in films, but they look cool so no one cares.
I'm not saying everything should be perfect, I was just pointing out he had a point. just because theres extraordinary things going on that are completely made up doesn't mean some things feel ridiculous because we know how they work and are being completely misused.
In Wanted, when a, not even sure what kind of truck the guy used, but the idea that a beaten up massive heavy POS delivery truck probably with lots of stuff in the back could keep up with an incredibly fast sports car is simply not believable, the other guy could simply have stolen a fast car instead and the whole thing would have felt more believable. Its not the most extreme case, but there are loads of points in loads of films where you cringe at how stupid things are.
Hell in Star Wars you can't help but be amazed that a jedi/sith can lift a hundred ton fighter with his power, but lifting his little old self and essentially flying is impossible.
It doesn't ruin Star Wars in any way, and its about the least extreme thing I can come up with, but there are moments in other films where it gets irritating.
Ok in X3, the bridge moving bit miffed me off no end, not least because the bridge didn't fit, wouldn't have stayed upright due to no supports after they put it back down. But this guy can make any metal into any shape and make it fly, somehow they traveled as a group from the middle of nowhere already, and stopped off close to their target to do something completely stupid and give access to support for their enemy, all ridiculous.
