You could say that about every Rambo film after the first brother.
Imho the first film is a genuinely good film and Stallones monologue at the end in the sheriffs station is a cracking film moment......it was a great bit of acting by Stallone I think.
That said, it’s not like you’re not going to not watch any Rambo film......it’s like Top Gun, The Glimmer Man, Road House.........80s indulgence for lads !
