In my experience with studio monitors, I have found them very enjoyable. I do, however, enjoy a flat frequency response. I like my Sony MDR-7506 headphones for the same reason. If you are considering monitors, there are some things that you should weigh first.
Studio monitors are often designed to have excellent response on-axis, but not so great off axis. This is why you will commonly see studio monitors with an extreme toe-in. The upside to this is that on the reference axis, you will have incredible sound that is very accurate. The downside is that such quality goes away pretty quickly as you move off axis. This means that if you're trying to satisfy multiple people watching a movie that only the person in the sweet spot will really get good sound. Now, not *all* studio monitors have poor off axis response, but it is a trait of most. In addition, studio monitors are meant to be used in a fairly heavily treated acoustical environment.
If you were to find a monitor that has good off-axis response (such as the 800-series B&W speakers from the 802N/802D and up), then it could be the speaker you're looking for. One of the best things about using a studio monitor is that it gives you a "blank slate". Unlike other speakers where one needs to compensate for uneven response, a studio monitor is naturally flat, so you have an easy starting place when it comes to customizing the sound how you like it. If you find that you don't prefer the flat response, that's easily fixed with a quality EQ (like the Behringer DEQ2496 or DCX2496).
I hope this helps you with your decision.
