The musical number sung by Cliff Richard (Jr.) seems out of place with the rest of the film. Even though it did happen in Alan's dream, it's out of place within that context too.
Alan's dream as a whole has essentially nothing to do with the rest of the film.
Designated Villain: The poor snake aliens only open fire on the martian explorers after they inadvertently blow one of their own to smithereens.
Funny Moments: During the pool scene, Gordon quickly pops up from underwater, saluting and saying "Thunderbird 4, at your service!", before diving back down.
Seconds later, Gordon throws a ball at Alan, who is reading a magazine.
Alan: Can't a guy get any peace around here?! (Tin-Tin laughs)
So Okay, It's Average: General consensus is that the set-pieces are as awesome as ever, but the film ends up feeling rather disjointed and unfocused- it feels more like two episodes spliced together than a single coherent entity since the second half deals with a completely different threat than the first half.
Unintentionally Unsympathetic: Much like the 2004 film, Alan spends most of his dialogue whinging about "not being appreciated" and the film completely vindicating this view without Alan changing or growing in any way.
The 2015 animated series
Broken Base: In "Breakdown", the subplot with Virgil's birthday and its treatment has divided some fans. Some feel it's amusing and lighthearted enough to be passed off as a joke, while others feel the brothers' treatment of Virgil's birthday and its aftermath bordered on Out of Character for the Tracys, celebrating a birthday without the birthday boy present and leaving them to clean up the mess afterwards.
It's Short, So It Sucks!: One of the complaints about the show is that episodes are only 22 minutes instead of 45.
Moral Event Horizon: In the later half of Season 2, the Mechanic begins work on "Project Sentinel", a satellite weapon that shoots lasers from space.The Hood found it too depraved to go through with, so the Mechanic has definitely crossed the MEH by continuing the project. From what we learn later it could also count as a sign that the Mechanic has crossed the Despair Event Horizon
Narm: The British voice acting can end up like this some times.
Padding: The utter insistence on showing the entire launch sequence of a Thunderbird. To its credit, if there are two or more of them launching, the clips and trimmed and interspersed into one sequence; but it still chews up between one and a half to three minutes of viewing time, further reducing time for the plot. While the original series itself was known for doing this, with the shorter running time, it can be particularly detrimental.
John Tracy, who went from the Un Favorite in the old show to the Ensemble Dark Horse in the new one. Although still the loner who is mostly locked up in his space station, he is utilized a lot more in this series. His role isn't just limited to Mission Control: he gets involved with several space-based rescues this time. Thunderbird 5 is much more mobile and tricked-out compared to the old series; it can propel itself through space and launch pods. John has a badass-looking Powered Armor, his own AI to squabble with, and even gets a love interest in the second season.
Some fans who found the original Alan's tendency to at times be moody and self-absorbed somewhat unlikable, especially from someone who's supposed to be an adult, find the more Adorkable younger Alan better by contrast.
Shocking Moments: A lot of what International Rescue does causes this, but the Episode "Deep Search" has to take the cake, the rescue taking place 10 miles under the ice of Europa. Yes, the moon of Jupiter namedEuropa. "Help is on the way," indeed.
Special Effect Failure: Some of the miniature work, usually whenever water is involved, can look rather obvious.
