While I loved the chemistry btwn Tom/Peter and Jake/Mysterio in this film (Jake was REALLY good honestly), BUT.... I agree... I much more enjoyed Homecoming. Don't get me wrong, FFH was really good an enjoyable (loved that I couldn't figure out everything from jump), but it was just missing something.
To be honest, I think you're right about Homecoming vs. FFH. I think in Homecoming we got to see more of Peter's personality a bit more. We got to see the characters a LITTLE more fleshed out a bit. But see...that's been my slight gripe with the MCU version of the Spider-Man films in the first place. I feel like the MCU version of Spider-Man focuses a little too much time and energy on the "Avengers", Tony, and other MCU characters, instead of focusing on PETER and his story, his motivations, his feelings, his challenges....etc. We also know very LITTLE (next to nil actually) about Peter's friends and surrounding back characters. Is it just me who is a little annoyed at this? We barely even know a thing about Aunt May. No mention of uncle Ben... No mention of even whether or not Aunt May ever grieved his death lol... I mean... Seriously... I just feel like the MCU version of Spider-Man films lack a lot of DEPTH to them.
I actually prefer the OG Tobey/Raimi SM films because they had heart and depth. You really FELT for Peter. He was struggling. This MCU version of Peter (while I LOVE Tom Holland in the role) is basically a trust-fund kid and hasn't really had to "struggle" much if at all! Not only that, but the writing can be a bit TOO "kiddy-ish" (imo). I mean, I'm glad they made Peter a real HS student lol, but did they have to dumb down the movie with a little TOO many silly jokes here and there? In Homecoming the jokes felt real and were actually pretty funny. IN FFH however, the jokes fell FLAT imo. I mean, how many bad teacher jokes can you have?
