Nostalgia and the brain

Is it true that the brain prefers things that it experienced during its early years of formation? Or that these things influenced the brain in some way and thus they're highly regarded by the human who saw them during formative years? This would explain vidja game, movie, radio show, tv, etc. nostalgia.

I think it's because children are less critical. They're simply more likely to no see the flaws. I recently downloaded pirates of dark water, which I loved as a kid. Now I'm seeing a cliched plot and pretty uninteresting characters. Hell, even things I am enjoying right now I'm criticizing in the back of my head.
I don't think any child goes "well, that was predictable" while watching a film they're enjoying.
