A Fantastic Movie

Yesterday afternoon I went to the cinima Cinema alone and watched the film 'Life of Pi', which was a 3D movie. I appreciated (the common term that would make more sense in this context is 'liked' or 'enjoyed') it very much because of the (a better way to make this sentence would be to say 'because it had' or 'because of its') wonderful story and the beautiful vision visual effects. I dont know what I will (it would make more sense to say 'would') do if I meet (met, because saying 'would', as I corrected earlier, changes the tense of the sentence) such an accident in the ocean. Maybe I will (say 'I may' or 'I might') start to believe in God or something that can make me strongly insisting my will to survive. This phrase doesn't make sense, and I am unsure of the meaning so I do not know how to correct it.
In the real life, I have a fragile heart. I mean, it is so easy for me to make a compromise to the cruel and rude realities, so I often learn lessons of life (better wording would be 'life lessons') from the meaningful movies. Sometimes it really works because I can find the laws of life, nature, or something else whatever, maybe it is a good way to make me calm down and think about my life. I really like and enjoy the process of the moving story.
After all (would be better to say 'in concusion' or 'overall'. 'After all' suggests opposition to what is previously stated, or a conclusion of a series of events), the 'Life of Pi' touched the bottom of my heart again. I love it. I really, really love it.

I'm sorry if anything I said was confusing, I'm very new to this. I hope you find these corrections helpful.

A Fantastic Movie

Yesterday afternoon I went to the cinima cinema alone (or 'I went alone to the cinema') and watched the film 'Life of Pi', which was a 3D movie. I appreciated it very much because of the wonderful story and the beautiful vision effect visual effects. I dont know what I will would do if I meet met such a thing an by accident  in the ocean. Maybe I will would start to believe in God or something that can might make me strongly insisting insist on my will to survive.
In the real life, I have a fragile heart. I mean it is so easy for me to make a compromise to the cruel and rude harsh realities ('rude' is usually personal), so I often learn lessons of life from the meaningful movies. Sometimes it really works because I can find the laws of life, nature, or something else whatever, maybe it is are possibly a good way to make me calm down and think about my life. I really *like and enjoy the process of the a moving story. ('process' here is a little too analytic)
After all, the 'Life of Pi' touched the bottom of my heart again. I love it. I really really love it.

*'enjoy' already implies that you like it. I can't think of something that I enjoy and don't like, can you?

When we say hypotheticals we usually use 'would' and 'could' because 'will' tends indicate that it will happen or that it can happen. I don't think you seriously believe that such a thing can happen! haha

Good work! It sounds like an interesting movie!
