I like Orihime, she is weird and odd at times, but she is nice and funny. At least she isn't like Mayuri Kurotsuchi. Although I wish they put more into Orihime's character, she seems like a healing cheerleader at times.
In part 1 she had her little random moments where she got all stupid and oblivious and that was pretty funny, I liked it because she added to the comedy side of things. The thing is when that trait of hers died out she started just worrying all the time which got kinda boring...
