No I love digital painting. The great thing about it is that it's so easy to pick up and use, but it's so hard to master. One of the reasons you might think they have a more generic feel is because the techniques mostly used in the industry exist to make relatively fast pieces of artwork efficiently. In my opinion, the mass production qualities that a digital painting has allows for a filter of artistic and creative thought, rather than having technique as the primary boundary for an aesthetically pleasing piece of art. Technique is still important, but when dealing with digital art's primary audience and medium (industry professionals using it as for quick visualization/ concept artwork) it's less important to get a message across as it is to make a tangible representation of an idea, and do so as fast and as affordable as possible.
Of course whether or not you like what the end result looks like is personal taste. Personally, I can say I absolutely love the look of transparent layering, quick rough brush strokes and implied details. I also really enjoy airbrushing too, and the techniques and look behind both mediums are similar in a lot of regards.
You always have to keep in mind that digital can masquerade as any other medium as well, it's much more versatile than anything else. Only the people who are more experienced can really push the limits of that though. I should find this one artist who immitated watercolor paintings and india inks with digital, it was really cool.
tl;dr digital is a pretty cool guy
