If you’re talking about streaming alone, then yes, Netflix is no better or worse than the rest of the pack right now. Streaming is still relatively in infancy, and the industry recognizes this is the future for film distribution. Because of this, everyone wants their share of the pie. Look for studios, distribution companies, media conglomerates, etc. to develop their own streaming platforms or enter long negotiations over rights, fees, profit-sharing, and so on. You’ve already seen some of this happening with Starz and Netflix. It’s very possible Netflix will be supplanted by something more superior (and they know it).
Now, if you’re talking about DVD rentals, I’d say Netflix is still king of the hill, for now. Their recent messy handling of raising fees, splitting services, and the like really gave them a black eye. They’ve retreated, but as I noted above, they know streaming is where the gold is going to be, and they’re running scared, trying to preserve their king-sized piece of the pie before someone swipes it out from under them.
