Well, I watched the episode in little 30-second chunks (due to a shitty makeshift internet connection which hates to buffer videos), but what I was able to piece together was the best I've seen in a long time. I loved the nods to continuity throughout, it actually seems as if the plot threads are coming together now.
I keep hoping that Donut and Sister are going to come back, but I doubt either are going to come back from the dead. At the very least we have a makeshift Shelia.

Also, did you read the other RvB announcement? They refilmed the entirety of seasons 1-5 (reviewing the scripts for those old episodes is probably what made them put in continuity nods, now that I think about it), so it doesn't have the same shitty filming quality as the original episodes did.
Compare:

I'm assuming they used the PC version instead of the Xbox version so they could get rid of the HUD and whatnot.
