If you have not synced with iTunes since you upgraded the Netflix app, then you can put the old version of Netflix back on from iTunes.
To do, delete the updated app from your iPad. Then, connect the iPad to iTunes. In iTunes, croll through the available list to find the Netflix app that's in iTunes. Ensure there is a check mark next to it or drag it to the iPad window. After that, sync the iPad to iTunes. You will then have the older version on your iPad. Just be careful in the future to not upgrade it from the App Store (and you will have to deal with the constant red update badge).
If the old app is already gone or updated, check your computer's Trash. If it is in there, save it to another location. Then, you can delete the app from iTunes. Then, double clicking on the old app will put the old version back into iTunes. From there, you can do the steps to transfer it over to your iPad.
Hope some of this helps. Good luck.
