Obviously with my involvement with Survivor Series I couldn't comment on that show, but I'll leave some quick comments for Raw.
First off, I really like the ideas of both the Elimination Chase for the WWE Championship and the title match itself between Triple H and Batista scheduled for the 15th Anniversary of Raw show. For such a momentous occasion you should have either a WWE or World Heavyweight Championship match (if not both), and I expect that the match will wrap up the Batista/Triple H feud before one of them moves on to a new feud for the Royal Rumble.
Stephanie in charge is okay, but what with Shane, Vince and Bischoff all being taken out, I have to wonder how long she'll be around. I can't say much on this angle since I know a few elements behind it, but as we've only discussed it and you're the one making the call with the thread, I'll be interested to see which direction you go in.
I think you may be in trouble with Big Show's character. Anyone in BTB (and probably in real-life WWE) will tell you that it's very easy to lose direction with that character. I'm not sure where he's headed now since John Cena will be occupied with the Elimination Chase for now, so hopefully you can either use him for your benefit (ie. to elevate another superstar) or maybe just let him go. I know how annoying it can be to find his character something to do!
One thing with Cena's promo (even if it is in recap) - I'm not sure how I feel about him saying it's "great" to have Undertaker back on Raw. Sure Cena's a goody two-shoes and he's a babyface, etc, and it's fine for him to say he respects The Phenom, but I'd prefer it if you gave Cena a little more edge by having him not so happy with Taker's return. Respect aside Undertaker is one of the biggest threats you can face as a superstar. This isn't so much a criticism as a suggestion to tweak Cena's character slightly so he doesn't feel the same as the PG CRAP we get in real life.
To be honest I felt like you've could've swapped the opening and closing segments. Whilst I imagine the Batista/Triple H brawl was okay, you could've used it to kick off the show in a big way. The announcement of the Elimination Chase and the return of The Undertaker could've given you a nice way to close the show, and perhaps given you the opportunity to have a real main event featuring Cena, Jericho and/or Orton. Again not a huge problem, but I just think swapping the two segments around would've given the show a bit more "oomph".
Benjamin beating Kane sucks.
Other than all that, I expect the Raw XV Anniversary to be a huge show and I really look forward to any surprises or shocks you may/should have in store. This was a decent Raw in the build up to that event and I know that you have some pretty cool stuff coming, so I'll keep reading, and hopefully, as you pick up more momentum with this thread back in action you'll get some more feedback from others too. Keep going !
