Do girls not like getting random gifts or small presents that show you are a nice guy?

I'm curious as to what girls think of when a guy gets her small gifts or just does random nice things. Like this girl I'm dating recently, she's really busy so I downloaded one of the movies she's really wanted to see and gave it to her. I sent her flowers just randomly cause its nice. Some other things I thought about is bringing her her favorite Starbucks drink when I pick her up to do something.

Is too many of these acts/gifts a bad thing? I guess I just want her to know I'm trying and that I listen to her and just try to do small things that would make her happy.
