Minor setbacks (spoils ending)

Rating: 7/10 (20 March 2015)

Yesterday, my mother rented 4 movies. We watched them at night and Big Hero 6 was the third on the list. I'm not much of a night owl, so by the time we watched the movie I was groggy and tired.
So before I begin, let me just say that I may be biased with my review, as we all are. Certain aspects of my life at the moment have most likely affected the way I have seen and interpreted the movie, let alone my mental state at that moment.
Anyways, the movie was great. Children would love it.
However, I had a few minor problems with the movie: Hiro had just met those people and they were already considered friends. They were his brothers friends to begin with but now they are his. Within moments in fact. I understand that they are young but most people do not befriend every person they meet. Second, Tadashi (Hiro's brother) had a wish. He wanted to help the world with Baymax but Hiro fulfilled that wish in a different context.
Instead of replicating Baymax (in turn saving thousands), he chose to keep Baymax to himself. Granted, he did save people with Baymax but a group of 6 can only do so much in comparison to the replicas he could have made.
Now let me just say that I was sleep deprived, I was even waking and falling out of sleep at one point (sometime after the halfway point BUT I did watch the ending)So for someone who hadn't been fully awake, maybe you shouldn't take my word. I do plan to watch the movie again one day, just not today. Let me clarify this before I receive any complaints about this. I LIKE the movie, I just feel bothered by these MINOR things. (to me they are minor, I don't know about you)
Watch the movie and tell me what you think. (Unless its been years past this post, then I probably won't be interested or even remember what movie is being spoken of)
