Grad Student life/housing/help?

Hey everyone so I just got into UH's Aerospace Engineering masters program and I'm SUPER STOKED!! Here's the thing though- I've never stayed in H-town for more than a day trip before.

So, this post is extremely vague, but does anyone have any general advice about living in Houston as a newcomer? Is the metro safe for females in their 20s? Is there a safe (not craigslist) way to find roommates in Houston that aren't necessarily grad students? Is there a safe-ish nightlife in Houston, and if so, where is it? What's the best movie theater in Houston (real question- who has the best popcorn)?

I've already been researching this stuff, but most of the results are from like 5/6 years ago and I'm assuming Houston's changed a bit in that time.

I know that's like a zillion questions, but any advice at all would be really appreciated!!

TL;DR- 24F moving to Houston in August, wants any/all advice about how to survive as a grad student/adult human in Houston
