Agreed could have been better, even more if the studio making these would stop thinking Doom is the only adversary the FF have. If they had left the Doom character out completely or only in flashbacks, really let Reed design a device to go to negative universe, as he seemed to be doing and made the villain be Blastaar with a hint of Annihilus pulling strings in the background, would have been so much better and they could have set themselves up for future stuff. Someday, someone will make a "family adventures in the unknown with powers" FF movie. Having said that, I thought the 4 playing the FF were decent and could have carried it on with better writing.
