This is a review of the new* film, "Avengers Assemble", which has Robert Downey Junior in it somewhere. The film itself is one I won't be going to see because, as I understand, it is a collection of comic heroes from other films all brought together to form one new film and I've never had the desire to watch any of the other films so it's likely I won't have much interest in this one either.
After filming the actors were probably tired, meaning the acting is possibly edited to remove the tiredness of the previous day's filming from the faces of those given primary roles. The action sequences, having been produced and collated in 2012, most probably have a lot of effects and I find that sometimes, while these effects are outstanding, they also take a lot away from the film and wow the audience into thinking the film doesn't need a plot. I prefer those films where people stand around talking for ages and then something happens and they all go "Wipe out. I didn't expect that." with absolutely no effects at all.
Even with the addition of 3D, which is a concept meaning essentially the characters are just made bigger to make it seem like they're closer (Think 'Father Ted') I don't think I could be enticed to watch a load of characters from other films I haven't seen come together and save the world from an evil presence that could have taken it's chance when they were all separate, insinuating it would have been easier to deal with.
I would suggest going to see this film if you want to as I can give you no real insight, however like all reviews this is my opinion and therefore not something you should consider before going to see something. If you like it you'll know fairly soon into the film and if you don't like comic action films then chances are this won't float your boat and you should have thought about that before your mate said he had tickets and you might as well go because you never go out any more due to 'the incident' and you thought perhaps he was right.
(*'new' refers to right now, when I am writing this post. If you come across it in 2026 and think 'this isn't new, what's he talking about? That film is beyond ancient' then it's because effectively you're from the future.)
