I don't think Vudu will make it in my opinion. However, since their is a forum, and the moderators say they will pass on feedback to the powers that be, there might be a chance.
Now I'm hard core movie/show watcher. I go to the movies 2-3 times a week, and watch 4-6 hours of Netflix a day.
After looking Vudu over here on the site, and my 360, I want to make a few suggestions. Mind you, if Vudu offered most of the suggestions I give, it would be all I ever need.
1.| Rent To Own: I know this may never happen due to contract issues, and the greedy studios and such, but I think if a person rents a movie or show enough times that the cost equals the value of owning it, he/she should automatically own the movie/show.
For example, if I rent "Blade" at a value of $5, but rent it 4 times over-time($5 x 4 = $20), then I should automatically own "Blade" on my fourth rental(assuming price is buy price $20).
2.| Too Expensive: I can understand new movies being $5 for a rental, but for movies over 10 years old? At that price I'll just stick with Netflix for $8 a month.
Movies(nearly new), should be no more than $2.50 a night. Movies 10 years or older should only be $1 night. Right now the system is backwards, newer movies are cheaper than older ones. I know that the pricing is close to what the competitors are, but they aren't a huge sensation either are they? Not compared to Netflix.
3.| Season Pass: I wish there was a season pass(rental, as much as you want) for TV shows released, and upcoming. Maybe $20 a season. Some people like to watch the same episodes over and over. The current the price per episode is a an insult, and the cost of a season is a bit high(yes, even the DVD's are priced too high). At the current rate, I don't ever see TV Shows being a success(but they are on Netflix).
4.| UltraViolet: very smart move and is one of the best things I've seen since Netflix. However, I see a huge problem. There should be a way to reverse the process. For example, I think there should be an option to get my movies from the Cloud onto a USB hard-drive. I'd hate to spend all that money putting everything on a Cloud, but then my internet go down. Then I cannot watch what I purchased. So this makes me skeptical about doing it. I just want to be able to request a backup of my Cloud. I wish I could just roll in Walmart, pay for a USB hard-drive, and get my Cloud backed up on it at the conversion station.
5.| Commercial Free: keep it commercial free. If you have to, I think the most that can be tolerated is a short commerical at the beginning of a movie, and that's it. I don't have cable or satellite TV. Which, when I visit my parents once a week, they have cable. They are paying $80 a month to watch commercials in my opinion. TV shows are 15-20 minutes long, but last an hour because of all the commercials. After having Netflix, I could never go back to that.
6.| Subscription: I think there should be a cheap option, where I pay something like $20 a month, and get 5 free movie rentals(HDX) and keep one movie(HDX). Perhaps a separate subscription for TV Shows like $20 a month, get 5 free rentals(HDX) and keep one season(HDX). I still think that pricing is high, but I could live with it.
Heck you could do $10 a month, get 5 movie rentals(HDX). That's one for each week +1. I'd do that right now if you had it offered.
Those are my suggestions. I know they are not easy ones, but I think they would make Vudu successful(by successful, I mean it's a name in every home).
Right now at the moment, I wouldn't use it mainly because of pricing. I'm already partial to Zune, although I only rent from it at parties. Just my 2 cents...
