I'd just listen to one of the one you are interested in to see if they have the yamaha signature sound, which is to say, forward, edgy, strident and a aggressive. Some may like this for movies but I'd prefer Denon to Yammies.
Or more accurately, in your opinion the sound is "forward, edgy, strident and a aggressive". I find Yamaha receivers to be highly resolving and neutral, in comparison to similarly priced receivers from other manufacturers.
Yamaha's HT receivers did have a (deserved) reputation for sounding bright and fatiguing for a number of years. However, IMO they have done a good job of taming the brightness over the past couple of model years and I feel the current mid-line receivers are pretty neutral. They certainly are not as warm sounding as HK or even Denon receivers, but IMO they definitely don't deserve their old rep for being excessively bright anymore.
A couple of things to keep in mind about Yamaha: first, their QC is excellent, I don't believe they have ever had a product line wide failure, either in software or hardware. I don't think any of the other name brand mass market manufacturers can say, the same, certainly not Denon, HK or Onkyo. I've owned many pieces of Yamaha gear over the past 25 years and not a single piece has ever failed.
Second, they are feature rich, particularly at their price points. Whether or not you will use or even want all the features they offer is certainly a valid question, but if you like features, Yamaha has them.
But Josh is right, in the end it is the same as always, you need to listen. Yamaha definitely does sound different and not everyone likes that sound. If you do like it, Yamaha packs a lot of value into their receivers at their respective price points, but if you don't like the sound, the features are irrelevent.
