L.A. Story - Is Steve Martin Underrated?

Okay, so I just re-watched L.A. Story, and I’m genuinely floored. I know Steve Martin gets love, but I think his performance in this is just… chef's kiss. He's got this perfect blend of cluelessness and genuine sweetness as Harris K. Telemacher. It's not just the wacky stuff, like roller skating through the museum -- although that scene is iconic. It's the smaller moments, the way he looks at Victoria Tennant's character, Sara, like she's solving some grand mystery of the universe. I mean, that first dinner scene? The awkwardness! It's so relatable, even if you've never had a talking freeway sign guide your love life, lol. Tennant's great too, playing Sara's bewildered outsider perspective to the hilt. But it's really Martin's vulnerability that got to me. I especially thought about his speech to Sara near the end, where he talks about maybe being happier with the absurdity and superficiality of LA. It felt so incredibly honest, and it made me wonder if he was drawing from real life experiences. Has anyone else felt this way? I get that it’s a comedy, and some of the jokes maybe haven’t aged perfectly. Also, what's with the random appearance from Rick Moranis, playing a Grave Digger?? But honestly, for me it plays almost like a really heartfelt character study wrapped in a silly rom-com. So, what are your thoughts? Am I completely off base in thinking this is one of Martin's most nuanced performances? And, does anyone else find themselves strangely drawn to the weird, almost Lynchian version of LA that the film paints? Is it just me?
