The Rock, WWE Criticized for Altering Cody Rhodes, Roman Reigns Storyline

The Rock may be cooking in the WWE once again ... but some fans aren't super happy about it -- 'cause it seems his return has knocked a major storyline off track.

Here's the deal ... last night, Dwayne "The Rock" Johnson got into an intense staredown with current Undisputed WWE Universal champ Roman Reigns at the end of ESPN's WWE SmackDown -- an insane moment seemingly setting up a match between the two wrestlers.

Indeed, rumors have been floating around today that they will fight in the next couple of months -- maybe at WrestleMania in early April -- and the online response ... is a bit lukewarm if we're being totally honest.

Sure, there are diehard Rock supporters who want to see their champ-turned-actor wipe the floor with Reigns ... but a lot of people are pointing to recent Royal Rumble winner Cody Rhodes and asking why it seems his story's now taking a backseat to The Rock's.

See, right before The Rock came out for his staredown ... CR talked about taking RR's title from him -- a right to challenge Cody earned by winning The Royal Rumble just last week -- and then seemingly stepped aside as he introduced The Rock to the crowd as if to indicate DJ's getting the chance instead of him.

That's all kinda shocking for fans ... 'cause Rhodes has been on the road to Roman for a while now while The Rock only recently hopped back into the ring.

As we previously reported ... Dwayne called out Roman Reigns back in early January during a surprise appearance on RAW during which he asked if he should be sitting at the "head of the table."

So it seems clear The Rock wants the title ... and that's where people are starting to voice their frustration -- because it sounds like the WWE's not really interested in furthering Cody Rhodes' journey anymore. Basically, they've backed a different dawg in the ring, and -- based on the X trend -- fans just aren't totally on board.

The major question here ... is it fair for fans to voice their frustration with The Rock at all? After all, the guy's not writing his own storylines as far as we know, and he's a legend in the sport, so it makes sense the WWE wants to use him.

But, Johnson recently joined the TKO Group board -- the governing body of the WWE and UFC -- and he now holds "The Rock" trademark ... so you could say he's got a lot more agency than your average WWE superstar.

Plus, Johnson's got a bit of a rep as someone who gets what they want in Hollywood. When he was working on "Black Adam," for example, he said he worked his magic to make a standalone film instead of first appearing in "Shazam!" ... a departure from the OG plan.
