I'm very impressed with the Marvel Superheroes range on whole. It's very rare that I have the funds to collect entire waves, so the fact that the Marvel range has only released five sets for its first wave is actually quite beneficial to me, as I've been able to buy all the sets. My favourite is the Quinjet, which might actually be one of my favourite Lego sets overall in terms of the build and look. However, as much as I loved the Avengers film, I'm still looking most forward to that elusive Spider-Man set, as he's always been my favourite superhero!
It's just a shame that Lego doesn't have the license for the Amazing Spider-Man really, I would've loved to have seen scenes from that recreated in Lego form...
