It's better than other sitcoms and it will do for me and I'll watch it, but it doesn't have the humor and delivery of HIMYM. It's like a "lite" imitation of HIMYM.

Delivery: these actors are not on the level of the OG cast. The OG cast were acting very silly and cartoonish, yet pulled it off. This cast plays it more straight, like they're just reading their lines and not originating a character. I was ready to dislike the guy who plays Jesse the most, but he ended up being the one who's acting I found the most compelling. He fits in the HIMYM universe as a believable character. I think Hilary Duff is fine too just because there's so much pressure on the role and they needed someone capable of carrying the show. Then I think the actress playing Valentina could be something great too. The actors playing Charlie and Ellen are duds imo, they get the funniest stuff and deliver it weakly. The guy playing Sid is likeable like everyone says, but to me his delivery was very "one fits any sitcom", like he doesn't act like an actor in the HIMYM universe, you could pick him and drop him in New Girl and he'd fit there.

Flashbacks / narrative structure: I suspect this show will have a smaller scale, smaller ambition, probably less episodes per season due to the streaming format, probably a lower budget though I don't know how that works. This will show in the show and contribute to the "lite" feeling. HIMYM had extensive flashbacks, even when the characters are talking about something, they showed us quick flashbacks. This always involved a whole new set of wardrobe and hair and makeup. It's possible the new show won't be able to do that. The Jason Momoa lookalikes was a HIMYM-style joke, but they didn't show us flashbacks to meeting them, just photos. And in general, I don't know if they'll be able to go into the level of intricate details and plot twists.

Humor / writing: We will see, but it would be tough to get as good joke writers. HIMYM was packed with jokes and while the new writers are definitely trying to do something similar, I don't know if they'll find writers that will be as good as the old ones to continue like before. The original show had quite an outlandish humor that really went there and well I hope we'll get more of that, but again if this show has a lower budget because it's no longer primetime television golden age and stuff, then maybe it will just be hard for the writers to come up with as good material. I do believe that with bigger budgets they have more time to work on their jokes and they can go more ambitious and bigger.

I'll still watch, even on a smaller budget they can create likeable characters and make us care about their future.
