Interesting but flawed

Rating: 5/10 (4 March 2014)

I was entertained by the movie, overall, but in the end I felt like it wasn't finished, and had almost nothing to transmit apart of the fact that it is wrong to eradicate a species.
I didn't feel what was the climax of the movie. The final battle, for me was just like a simulation and I remember wondering how could the "real" battle fit in the remaining space till the end of the movie? Of what use were those training games between teams, and how would that aid with ship fighting? The only connection with the final fight is that drones dig a hole through the enemy and the blast passed through...
Ender was going to give up after he injured the other kid in the bathroom, but his sister managed to convince him to go back with just 2-3 phrases. And the final argument was that if he doesn't try, he will not succeed. What had that to do with the injured kid and the guilt he felt? What strategist would leave the Earth defensless and go light-years away to fight the enemy with his best ships? What if the enemy was already close to Earth, and launched an attack? The whole idea to use kids because they have better minds is ridiculuos. No one in his right mind would do that. What did they need to process, anyway? That the enemy was swarming and coming to fight them? The end is bizarre. How could a queen be so close to the human base and they didn't find it? The special effects and the acting weren't bad, but the story is not plausible.
