The broadcasting watchdog is considering whether to investigate following complaints that a bus crash on EastEnders mirrored recent terrorist attacks.
The terrifying incident left several characters in the soap fighting for their lives.
Some compared it to the Berlin attack, when 12 people died after a lorry was driven into a Christmas market in December.
Regulator Ofcom said it received 29 complaints about Tuesday night's scenes on BBC One and is assessing them before deciding whether to investigate.
Viewers objected to the storyline, which saw a bus crashing in Albert Square after the driver had a heart attack, saying it was insensitive in the light of real-life incidents of vehicles being deliberately driven into crowds.
A spokeswoman for the soap previously said: "EastEnders is a fictional drama and the crash was not based on any real-life event. We are always mindful of the content within our episodes."
Actor Jake Wood, who plays Max Branning in the soap, thanked fans on Twitter following the episode.
He wrote: "Thanks for all your comments on tonight's @bbceastenders. So proud to be a part of this show #eastenders."
Fans of the show were divided over the storyline on social media.
One viewer tweeted: "Am I the only one disappointed in #eastenders for the bus crash storyline? Considering the news in recent years, I'm finding it poor taste."
Another soap viewer asked: "Anyone else think that #eastenders was in poor taste tonight so soon after Berlin market terror attack?"
Some also praised the show, with one viewing commenting: " The last few episodes of @bbceastenders have been absolutely phenomenal ... hats off to all the cast & crew involved #EastEnders."
Tuesday night's episode saw the cast dealing with the aftermath of the crash and fans have been speculating as to whether a major character will be killed off.
A possible death aside, viewers were also quick to point out the length of time it took for emergency services to arrive at the scene.
One commented: "Surely emergency services would get to a major incident sooner than it has in walford #eastenders."
