Orange is a nice anime. If you're looking for an anime that's fast-paced, comedic and unpredictable, then you should definitely look elsewhere, but that, in no way, means that this anime is bad.
Orange is a simple, slow paced high school drama, but, unlike many others of it's kind, it remains realistic. Of course, these are still teenagers, so it isn't unlikely for the viewer to get frustrated by a few actions (or lack there of) caused by misunderstandings and teenage insecurity, but the drama makes good use of these moments for character growth and other such things.
Orange is an anime makes you feel all sorts of emotions, good and bad, while managing to finish its story nicely. If you're looking for an anime that makes you feel and ponder, then I think Orange would be a good choice for you.
