Striking visual and thrilling music with a rather weak plot and lack of engaging characters. Tron Legacy is a quest of "discovering long-lost father" and "getting back to reality" with a very shaky progression from beginning to the end.

The main question of the plot - the desire to perfection and admittance of imperfection - is never clearly explained. What constitute a "perfection" in a system or program? Why was The Grid "perfect"? Why was the ISOs imperfect - especially when they were thought to reshape our physical world? We get the characters shouting each other about perfection/imperfection but never get to know what it's like. This also brings us to the question of ISOs: who are they exactly, why and how can they bring changes to our physical world? The quest of bringing ISOs to the physical world is made like it's a big plot point, only to be never explained [spoiler]and just became a romance subplot for Sam, the main character[/spoiler].

The characters are not engaging. The plot revolves around tech wiz Flynn (Jeff Bridges) and Sam (Garrett Hedlund), a missing father and his son searching for him, but we don't get to see them interact enough to form a bond. There are a couple of scenes and dialogues trying to joint the relationship, but it hangs on there without a proper intertwining. And not let's speak of Quorra (Olivia Wilde), who seems to be there just for the sake of being a female character (barely see other females here) as Sam's romantic interest [spoiler]who, in a predictable move, turns out to be a monumental plot device - the ISO[/spoiler]. They have a couple of dialogues, but it all feels a little too janky, especially with Sam never questioning why and how Quorra gets along with his father.

The tech simulation, neon lights city of The Grid is aesthetically very pleasing to see, and the film does very well in this. However, I'm a bit puzzled for quite some time to how its citizen would behave. If The Grid was just a program, why do they all behave so humanely? Intruders are not easily detected (unlike computer program), people get so easily emotional, with secret motives and can be deceived. Took a while for me to make sense of it - that this isn't really a program, but a simulated human city (which is pretty advanced considering the setting the movie takes place).

If you're just in for the visual and music, it's not bad at all - almost pleasing. But there isn't much to be experienced other than that.
