From my perspective, Max Berek got it right in the first place when he designed the first lens for the Leica camera. The Elmar 50/3.5 is almost the perfect lens in my opinion, and it is almost certainly one of my most used lenses. It is very light, very compact, and very robust. Of course there are other 50mm lenses from other manufacturers that meet this same criteria, but none that I know of are so small during transport.
Not only does the Elmar 50/3.5 take terrific photographs, but the depth of field, even when wide open, is still very good. It almost always produces sharp, in-focus, photographs even if the photographer makes some minor focus errors because the depth of field is so forgiving. In my opinion, f2 and faster apertures don't provide that latitude and are very unforgiving in this respect. For those who are not out photographing all the time this is a bigger problem than many of them realize. I think it is one of the biggest contributors to dissatisfaction among amateurs who find it difficult to consistently take sharp photographs.
As for being boring, that is not an inherent feature of any lens that I have ever used whether it was wide angle, normal or telephoto. But it can be a feature of the photographer. Some of the most exciting photographs I have viewed have been taken with the "normal" focal length for the given film format in use.
