I've had a watch of them all so far, and here's what I thought of them (worst to best):
Z! True Long Island Story - I watched like the first 30-odd episodes on Ryder's channel but just cbf with it anymore. Not because it's shit, just cbf with it. Not really "the worst" but I just don't watch it.
Superstar Toyz - At times I found it to be awkward. I just couldn't believe Del Rio was actually shopping for cars because it was so obviously staged. Whatever, we'll see who else appears down the line.
WWE Download - I thought everyone was unfair when slamming this show from the get go as I didn't mind the first episode, but I only got through about a quarter of the second. I tried watching the first again but couldn't get through it. If that show is to keep going, something needs to change. Idk what it is but it's just not that great, which sucks because I like Ziggler.
Are You Serious? - Idk about this one yet. It wasn't that bad and I definitely see potential in it, but the puppet ruins it for me. It was the worst part of the first episode because I found it to be silly. Again, though, it has potential and I'll keep watching.
WWE Presents - I didn't mind the first episode, especially considering The Bella Twins looked banging. For anybody that enjoys history, have a watch. Interested to see what else is put up.
Backstage Fallout - I think it does it's job, which is to further certain events that occur on Raw and Smackdown. It's good and shouldn't go anywhere.
Outside The Ring - I thought the one and only episode was cool, with The Usos cooking a Samoan meal. I'm not a cook and don't care for the recipe, but just the segment itself I liked. The Usos were pretty relaxed in it and you got to see their personality shine through too, so that was nice.
WWE Inbox - I like it, find it very interesting and a great way to get to know the Superstars on a personal note. There were a couple of reasons why I really liked the second one with some of the NXT superstars. The fact Kaitlyn was in it instantly made it amazing for me, but I have to admit Maxine is growing on me as I'm finding her hotter and hotter everytime I see her. Not only that but Tyler Reks seems fun and has a great personality, something I wouldn't have known if I didn't watch this. But what takes the cake for me in that episode is the fact I was seriously close to crying I was laughing that hard at what William Regal said. Absolute gold!
Foreign Exchange - The moment I saw Santino had his own show I knew it would be good. I've seen both episodes and the guy is fucking hilarious. For me this is the best show they've got, but really, did anybody expect something with Santino NOT to be funny? I know I didn't.
