Watched it, loved it, didn't like the sequels.

If every violation of physics made me hate a movie, I wouldn't watch any,
ever

Likewise.

Well, I don't know, a few get it right. They are a minority though...

  White noise has been exchanged for mpeg artifacts. Not much of an
improvement, IMO.

  Moreover, one could argue that in areas with bad reception the situation
has got worse. With analog TV bad reception means more white noise, but
at least you get to see and hear something, which may be quite important
if you are eg. watching the news or weather report.
  With digital TV, however, bad reception means that the broadcast stops
playing at moments.
  The human visual system is more permissive of noise than intermittent
playback. Intermittent playback may even mean incomprehensible message.

  Inside the virtual world anything is possible, so no physical laws apply.
In the real world, however, they should still apply. Of course some of the
things might be explained by extremely advanced technology ("any sufficiently
advanced technology is indistinguishable from magic").

Not necessarily white - multipath interference results in ghosting. But 
then, so do certain compression artifacts, so...

Indeed. Analogue goes from crystal clear to utterly unrecognisable in a 
smooth progression. Digital goes from crystal clear to nothing at all in 
a single big jump.

Still, digital gives you the possibility to use error-correcting codes 
to try to combat poor reception. And boosting a digital signal offers 
more possibilities for error correction than in an analogue system.

Clearly my TV must be *very* bad. I've yet to see any compression 
artifacts in any digital broadcast or DVD. (Except some of the DVDs I 
burned myself...)

That's true. And that explains why people can fly and survive impossibly 
long drops and so forth. But as one reviewer pointed out, "Trinity can 
defy physics. But the guy she's attacking is just a normal guy. Why 
doesn't such a high-placed kick make him spin rather than just 
translating backwards?" (The answer, obviously, is that the latter is 
drastically easier to film, and still looks cool.)

  If Trinity can manipulate the simulated physics in the virtual world,
surely she can also manipulate the way in which her victim physically
reacts to her kick?

Plausible. But then, why not just manipulate the laws of physics so the 
man goes flying without having to physically kick him? :-D (Or better 
yet, make it so all the oxygen in the room mysteriously vanishes...)

But then, that wouldn't be very exciting, would it?

Given that it seems that these guys can only "bend" the laws of physics, 
rather than utterly disregard them, maybe they can only enhance or 
reduce physical effects that are already happening or something? Who knows.

OMG... geeks! o_O

	That's a stretch. It's simpler to say that whoever designed that
virtual reality didn't know much physics...

  I think the movie establishes that while they can manipulate the
physics of the simulated world through their neural connection, it's
not easy and what they can do is limited. They are not all-powerful.
(After all, some people such as Neo can manipulate it more than others.)
It's plausible to think that eg. making a kick helps them manipulate
the physics more easily than trying to create the same effect without
the kick since performing a kick in the virtual world triggers some
physics simulation routines, which they can more easily just slightly
nudge to get a stronger effect. It's just a much slighter "tampering"
of the physics engine routine than it would be without the kick.

  It sounds plausible also with the overly long jumps: They just can't
manipulate the system to transport them to the roof of the other building.
They have to trigger the physics simulation by making an actual jump, and
then just "nudge" it slightly to boost the jump.
