A lot of good ideas from the people who posted in this thread.
I think people, in general, are a bit harder on SmackDown than it deserves. Sometimes, yes, it's garbage and nothing interesting happens. Okay, maybe a lot of the time, and that's probably why even when there is a good SmackDown people are hesitant to say it is because they are so used to just saying it sucks. Even though people say they want quality matches, storyline progression, less tag team matches and have something really worthwhile happen on the show I'd bet if most of us were charged with actually keeping up with that if we were in charge of the show we would be having the same problems. So I do think it is easier said than done to make SmackDown 'better', but there are a few key things I think they can do, and do more consistently.
Now, I've seen SmackDown this Friday due to the international airing time and I won't spoil any finishes (even though you can see them all if you are on this site and read the spoilers) but I will say I believe tonight's SD is an example of a good episode. We'll have to wait to see the ratings, I hope to see they are good to confirm my feelings but I'll break down what happened and say why I think it was good, or where it could be improved and what SmackDown should continue to do.
SmackDown started with a 8-man tag match. The Usos, Mark Henry and Big Show vs Erick Rowan, Luke Harper, Star and Goldust. Even though I don't like tag matches that get above 6-men, this one was actually good. The pace was kept up, each Superstar got in some offense and the finish was solid. Only thing that I could think of that would make for a 'must-see' OMG moment would be a Superplex with like Big Show, Mark Henry, Harper and Rowan somehow form the top turnbuckle that then destroyed the ring! Of course, that would mean the match would have had to end the show, so considering the placement on the card, the match was good.
Then was Bo Dallas vs Justin Gabriel. Jack Swagger was at ringside with Zeb to build more on the Dallas/Swagger feud. The match was decent. Gabriel has a cool new look now with a good entrance theme and got in some decent offense so it wasn't really a squash match. But a good match for what it was supposed to be: building up Bo Dallas while building more tension between Swagger and Dallas in this mid-card feud. Good use of SmackDown to focus on Superstars who don't often get much time on Raw.
Paige vs Summer Rae was next. Layla at ringside and AJ at commentary. Honestly, didn't watch it until the very end. Each female is a solid wrestler but I just wasn't interested in this at the time, but that's more my opinion than anything 'wrong' with the segment. So it did what it was supposed to do.
Next was Mark Henry vs Rusev in the International Arm Wrestling competition. Say what you want about arm wrestling competitions in a scripted show but hey, it was something we don't see all the time. Really, how many arm wrestling competitions have there been in WWE in the last 10 years? Not really many. So this was a good use of SmackDown time to build the feud between Henry and Rusev.
Dolph Ziggler & R-Truth vs Miz & Sandow. Fun and good match. This is and example of furthering storylines on a SmackDown and something interesting happening because Ziggler called out R-Truth, or should I say, R-Ziggler to be his stunt double in response to the Miz and "Miz"dow thing going on and it was funny and good. Not a super long match, but it didn't need to be to get the point across. It's storyline progression for IC title. Only thing that kind of sucks about it is that it wasn't he Main Event so it means those guys aren't really main event material and so really maybe this should be the US title feud, but none the less, who are we kidding? The IC title IS mid-card and so even on SmackDown it will usually be there. It was also only one spot out of the main event, so that's probably a good sign anyway.
Main Event of the night was Jericho & Reigns vs Orton & Rollins. Another good match. Building tension and story between these Superstars, in particular, Jericho/Orton and Reigns/Rollins. Each Superstar looked good and since these are related to matches on the NoC PPV it made sense to use SmackDown to further this more. The one thing I don't want to see is this as an exact rematch on Raw, which sadly, may indeed happen. However, it is not a problem of SmackDown, more a problem of Raw.
So, there you go. SmackDown can be done well. It only sucks every time if you want it to suck every time. Some nights it actually is well done. Like I said, problem is consistency. If tonight's SD was good but next week we get some garbage like 2 separate Divas matches, a 10-man tag match with every tag team on the roster for no good reason, Bo Dallas vs El Torito and Randy Orton vs Sheamus for the 1000th time, then I could see people getting upset with the show for not being 'worth it.'
