Reed is a bit of a tricky character, at least in my mind. There really is no "right" or "wrong", just a matter of what stories you read and what characterization you prefer. I think he's easily someone who can come off as cold and uncaring because he puts logic first, and I'm glad that they touched on that even a bit in the movie. He's a good man with a good heart, but he's not Dr. Strange- he can't see every single outcome. He can think of every outcome, granted, but I think his brain will always prioritize logic over emotion. In the wrong hands, that could easily come off as cold, but Pedro is such a charismatic guy that he can make anything charming. And First Steps is, I think, a movie that leads with emotion at the end of the day. Family, love, sacrifice, being parents, etc. I kinda liked that Reed's views were challenged. I'm sure he'll have more than enough time to lecture in future movies.
I'm sure part of his characterization also stemmed from the fact that it wasn't an origin movie. If it was, and the team was slowly being built up into superheroes, we'd see more of his logic. As such, there's just too much to cram in to an already truncated movie (maybe in some of the cut footage there's a bit more of his genius). Maybe they didn't want to show too much of it because, especially in this day and age, people just want to go to the movies to escape, not be bogged down by jargon. Granted, it's all in how they play it- having his smarty-pants speech be undercut by Johnny or someone making a snide comment could work. That's why I'm excited to see how he plays off other heroes who aren't used to his quirks- I can see some really fun interactions.
And, while I hate to be that guy, I do think there's at least a liiiiiittle bit of that built-in bias with Pedro and just who he is as a person. Again, he's so charismatic to so many different kinds of people that he ends up alienating a lot of people too. Overall, some folks are just getting tired of seeing him in so many projects (which is kind of out of his control- it really comes down to when things get released, which he has no say over). Ladies love him, but he's not every lady's cup of tea. Lots of guys don't like him because not only does he steal women's attention, but he's not the traditional macho masculine guy, even if he can play it pretty well (Joel, for instance). He is, like it or not, at least a little more in touch with his feminine side (it kinda seems like the worst kept secret that he is- or could very well be- gay, and while it's none of my business either way, I know that that puts off some people). There's also the implicit bias of his race. While certainly he can "pass" as a white guy (as silly a concept as that is), he's Hispanic/Latino, which a lot of racists don't like him snatching up roles from white guys, especially if the role he's taking has been traditionally white. And there's that whole ridiculous smear campaign as of late trying to get people to think he's some creep because he's comfortable around women and vice versa. So he's got a lot going against him, but he more than makes up for that in charm.
Anyway. So as not to bog down the conversation with too much heaviness, I think he's a great fit for the character. I'm really looking forward to seeing where he- and the rest of the F4- go from here. I'm also really kinda happy that we don't have a major MCU project (film) for a bit- I really need to get caught up on some of these shows- namely Echo, Daredevil, and Ironheart. I gave up on What If? and don't really feel the need to go back. I'm sure I'll get around to Wakanda, but I don't really feel the need to rush into it (don't even know if I've seen a trailer for it, to be honest). I'm surprised I haven't watched Spidey yet- I used to be all over the Spidey cartoons, but I keep forgetting about this one. I know soon there'll be Wonder Man in there too. Marvel's gotta give me time to catch up!
