How much disposable income do you have? If you sprang for Sony's PlayStation Plus service for either $50 or $18 (depending on how much of a commitment you wanted to make), then you're currently eligible to download a special preview version of Hulu's premium offering, Hulu Plus, for the PlayStation 3. For an additional $10 per month, you can watch some Hulu programming via the PS3 on your TV, but is it actually worth the extra cost? I'm not kicking in for this one, so instead I'll point you to Gizmodo for an answer.
[T]he process is just like using Hulu in a browser. Click on one of their highlighted shows. Pan through episodes. Subscribe. Rate. Etc. I didn't notice any feature (that I wanted) missing from Hulu on PS3 that made me long for the web interface. And as a bonus, if you choose to look around the menus while watching a show, the video will just shrink down into the corner of your screen...a miracle to those of us used to Netflix.
As for watching clips, the experience, again, is akin to the PC. Click whatever you'd like, then prepare for a 30-second ad. Personally, I'm fearful of mankind deciding, like we did in the days of cable, that we'll pay for a monthly service that also has unskippable ads. But sidestepping that debate, I'll just complain that ads need to be audio balanced with their respective content. While watching Modern Family, a show that tends to be quieter than most, I encountered an ad that blared through my speaker system at more than uncomfortable levels. Sony and Hulu, please remember that I have neighbors and a soft spot for my hearing. Fix this tiny issue.
As for the video quality of the actual content...it's decent if you consider that we're talking about streaming media, but objectively, it's mediocre at best. You can actually toggle 3-4 bitrate settings depending on the particular media content—a handy feature that will allow you to get the best possible signal every time. Cranked all the way to 3.4Mbps HD (max), I thought the image was a bit worse than HD on my DirecTV...which is in itself so lousy that I don't really consider it HD despite the "HD" moniker.
Between all of the digital cable channels I get, my Netflix subscription, and my video gaming to-do list, I have more than enough entertainment content to explore and enjoy as it is. I just can't justify paying another subscription fee to a service that offers the same content I can get elsewhere for fees I already pay. I'm glad to see Hulu on a console, but it's a shame that it has to be the premium Plus service exclusively.
