My thoughts on every Jonathan M. Shiff Productions first EP except Kelly which you can't even find it's 1st EP anywhere, but only just their first EP from Season 1 & like before just some pics without doing screenshots so this is all I can found via random pics.
Ocean Girl S1 EP 1 - The Girl in the Sea, ah yes our introduction to Neri aka the Ocean Girl, the Bates family (Dianne and her two sons, Brett & Jason), Winston, ORCA and almost everyone from there. As far as first EPs go, it's pretty good & for what's to come later. It's good overall.
Thunderstone S1 EP 1 which doesn't have a EP title is another good start to the series introducing us to Noah Daniels, his family like his sister Becky, his parents Liz & Simon & North Col with a nice end seeing the Nomads lead by Arushka. Honestly solid EP introduction.
Horace and Tina EP 1 - Arrival, man what a trip this was, introduces us to Lauren moving from Canada to Australia living with her mum meeting & living with her stepbrother Max & stepfather Steve, also seeing the animatronics who guess that is & the many side characters at least in this EP anyway.
Cybergirl EP 1, nostalgia biased aside, I really like this EP on showing Cy, Jackson and his father Hugh, Isaac & Xanda and of course the side characters and River City.
Pirate Islands EP 1 - The Game, so much going on, the main cast Kate, Nicholas & Sarah and then Mars, Blackheart & his crew, Carmen and the Castaways, the whole game itself & yeah good EP.
Wicked Science S1 EP 1 - The Gift which again I liked, Toby, Russ, Dina, Elizabeth, Verity, Garth being the main cast & the side characters at least in Season 1 until Season 2 completely changed them for the new ones including Sacha as the main girl after Dina left.
Scooter: Secret Agent EP 1 - Operation: Destiny it has a very goofy & silly introduction to well Scooter and introducing to the main cast like Melanie & her dad Attilo and little brother Mario, Katrina, Gordon Mckenna and his gang like Fridge & Donald, Tiapan & Danny, fun EP.
The Lost Treasure of Fiji EP 1 - Game On which I count as separate to the original Pirate Islands despite how I think of this show as a whole, it's alright with introductions to Tyler, Allison, Kirra, Marty, a different Blackheart, Lilly and the village people to which Sol is the main one they focus on.
The Elephant Princess S1 EP - Coming of Age, I liked the opening first off, introducing Alex & her friends Amanda & JB, Kuru, Vashan, Diva, Omar, Alex's family the mum & dad Anita and Jim, her little sister Zoe, Manjipoor which is the kingdom who Alex used to live there, like Wicked Science some or most of these guys & places sadly don't return in S2.
Lightning Point EP 1 - Wipeout, it's decent for me, once again we got our main cast, Amber, Zoey & Kiki, along with Luca, Brandon, Madison, Amber's mum Olivia Mitchell who is a policewoman and some of the side characters that appear in this first EP.
Reef Doctors EP 1 which like some of them has no EP title, It is actually pretty good. First off main cast introduced, Sam, Olivia, Freya, Gus, Rick, Toby, Nell, Sam's estranged son Jack, Sam's ex husband Andrew, Sonny & Malcolm aka Sam's rival.
The Bureau of Magical Things Season 1 EP 1 - Magical Mishaps, the only one that felt like two part story due to it's ending but I digress, probably one of my fav first EP introductions due many things like the music score, meeting up Kyra, Lily, Imogen, Darra, Ruksy, Kyra's stepdad Steve, her best friends Mathilda & Peter, Professor Maxwell, Doris this dog that Kyra walks with who she can communicate with, appears again in EP 4, Ladder and the Library of Magic & oh yeah River City again.
So what do I think of H2O: Just Add Water S1 EP 1 - Metamorphosis & Mako: Island of Secrets S1 EP 1 - Outcasts, the last ones I have to say about? Well the former is ok, the one thing that sadly holds it back is the acting but I understand why because Phoebe, Claire & Cariba were just starting out on their acting career, while some of the others like Angus, Burgess had at least some acting crops with stuff prior.
While the latter was actually a good introduction EP with almost of all of the main & support cast appear at the time, Sirena, Nixie, Lyla, Zac, Cam, David, Evie and yeah Aquata, Sirena's sister. Carly & Rita as well as Zac's parents don't appear until EP 2 & 3. Yeah unfortunately or fortunately depending who you ask, Lyla, Nixie & much later Sirena, they are not in S2 for the former two and S3 for the latter.
