How will life on Mars with oxygen be?

Hello, I am sure we all have seen articles about how they are planning on making Mars habitable for Humans to live in. What do you think about that. I think that will be cool, because image and movie's I have seen, always show that we can see space from the surface of Mars (I am not sure about this), but I think it will be nice to live in a place where you can see other planets 24 hours. This just reminds me of the film Elysium, that movie is really awesome and the writer is really great. In that movie Earth was over populated, so they had to build an artificial planet where the rich ones live. That planet must have been extremely expensive to build. Just that that planet still looked like Earth.
Which brings me back to Mars, how will life on Mars really look like? Cool.
As far as when we are moving there, we don't carry all these dangerous animals like snakes and it's kind, I will be very happy. If mosquito doesn't exist there, I will be extremely happy, because they are one of the most annoying insects ever. Life again might be safer. How will they fix the gravity, well, considering how far we have advanced in technology, they just might be able to do that.
Thank you very much for reading this post. What do you think concerning how life on Mars will be like, comment below.
